My Cat Has Lost Appetite and Weight with Labored Breathing

I certainly could use some advice from you fine people. I have read a lot of the articles provided on this website, but much of it was too generalized for my specific questions.

Anyhow on to my issue. In the past week I have noticed some changes going on with my 15 year old cat Holly.

1. She was going to the cat box regularly, but her feces was coming out rather small and thin.(Not to mention a bit hard). In the last few days I have been watching her closely, and rarely see her visiting the box. After daily inspections, I am noticing very little to no business done.

2. The past 2-3 days she hasn’t been eating much at all (due to current finances, we could only afford dry food). We did get some wet food for her yesterday, but she barely touched it.

3. She hasn’t been drinking water as much as she usually does. This concerns me because it has been very warm and humid here.(80+ degrees Fahrenheit.)

4. When you own a cat for 15 years you tend to notice where they go when they don’t feel good. Lately Holly has been going to that place in the house, behind the tv stand.

5. She has lost some weight, and I also noticed her breathing has changed. It has become shallow and labored.

6. She has become unresponsive when I call her. This is out of the ordinary for her, because she is a cat that loves attention. The only thing that she has been doing that IS normal, is sunning herself near the patio door.

I am inclined to think it is hairballs, because she has been off her weekly regimen of hairball prevention for almost a month now.(Due to finances) But I fear that it is something worse, like anemia.

So, with all that information, can anyone advise me on what is going on with my kitty?

Hi… thanks for visiting and asking. It seems to me that the bottom line symptoms are a loss of appetite and loss of desire to drink plus labored breathing. Not going to the litter is, it seems, a consequence of loss of appetite. Her loss of weight also seems to be a consequence of that.

A loss of appetite is a generalised symptom. It is a symptom of an ill cat just as we lose our appetite when we feel ill. Unfortunately it is a sign that does not direct us conclusively to a single cause.

One other factor that might be significant is that she is 15 years of age. A good age and an old age for a cat.

All I can do, I feel, is to see, if I can link age with lose of appetite and a likely illness.

One obvious possibility is mouth disease but this should be noticeable when the mouth is opened. Old cats are more likely to have mouth disease. I feel that this is not the cause, however.

“Weight loss is serious in the aging cat”1. It can be caused by kidney disease, cancers, periodontal disease (mentioned above) and loss of smell plus other causes.

The advise from a good vet is that weight loss is an “indication for a veterinary checkup.”1 Compounding that advice, labored breath also indicates a vet’s attention. These are two symptoms that are considered “danger signals in the elderly cat”.

Sorry if this is upsetting.

Kidney failure is not uncommon in elderly cats. The first signs are increased voiding and drinking so this may not be the cause although apathy, sluggishness and loss of appetite and weight are symptoms as are brownish discoloration of the tongue and dry hair coat.

Heart disease is another possibility. These are speculative. One thing definite is indicated however, which is this might be serious and in which case a vet’s visit is called for and I know how much most people don’t really like that for all the usual reasons including cost which may be a factor for you.

I have been through my reference books and there are many illnesses, some serious such as Feline Infectious Peritonitis that can cause the symptoms that you have mentioned. Incidentally, a foreign object in the mouth or throat would cause coughing so is not applicable it seems to me

One last possibility is poison but this seems unlikely.

Thank you, Holly’s mom for the detailed symptoms list and especially for the last update. I am sorry for your loss.

You might have been describing our cat when you listed the symptoms. We will concentrate on making our old kitty’s last days comfortable and pain free.

Feb 21, 2011 Late Update
by: HollysMom

I don’t know if anyone checks this particular topic anymore but I wanted to give another update.

It turns out the infection was worse then I thought. After taking Holly to the vet for a checkup on the 13th of August, On August 15th she passed away.

I was with her in the end and it was a very emotional time for me. I still get upset sometimes, even as I am writing this I feel very sad.
She did have a good old life and I tried to do my best for her.

I am sorry I didn’t come back sooner to update, I had a lot going on.

Hello again Holly’s mom.I’m so glad you came back to tell us how she is and I’m happy for you that it’s a treatable illness she has.
It just shows how we can jump to conclusions when not actually seeing the poorly cat as it did sound like Holly had a growth in her tummy.
It’s always important to see a vet and not take for gospel what anyone else thinks.
I don’t envy you the month’s anibiotics, most cats are terrors to dose lol
But you’ll get through it as you sound determined and you obviously love Holly very much.
I hope she’s soon better,do let us know if you can.

Well, 500 dollars later I have good news on Holly’s condition.

The vet just called me today about her blood test and it turns out she has a lung infection. Thankfully it is treatable and all of her other organs are in good shape.

The vet was speculating on cancer so the last few days have been very emotional. But with the blood test being negative for cancer its all well and good.

Holly will have to be on antibiotics for at least a month, but I would rather force feed her antibiotics every day then to put her down.

She is going to be eating special food until her appetite comes back. The vet also has her on vitamins and Pedialyte because she is slightly dehydrated.

Thank you Ruth for your responses, thoughts and prayers.

With a lot of work and some time, hopefully Holly will be back on her feet and back to normal.

Hello again, it’s good news Holly’s gums aren’t pale.
I’m so glad you are taking her to the vets,if you can’t borrow the money explain that to them and they may agree you can pay so much at a time.
I will be thinking of you and Holly and hoping and praying it’s nothing serious !
Sorry if I scared you but I know from experience the longer you leave a poorly cat untreated the longer they take to recover.
PLEASE let us know.

Thank you for the quick response and posting of my issue with Holly.

@ Ruth: I just checked her gums a few minutes ago and they look normal.

I will be following up on this by taking her to the vet, even if I have to beg family members for a loan.

Thank you again for the quick responses. I will update you guys as soon as I know something.

Only a vet can diagnose Holly’s illness but I’m very much afraid it sounds like she has a growth in her insides.This would cause her bowel movements to come out thin and then hard and eventually she will have a total blockage. She is probably bleeding internally which will be causing the shallow laboured breathing.
Cats also tend to hide away when they are ill,they withdraw from you and don’t respond as they used to.
Look at her gums,if they are very pale she is definately bleeding internally
I’m really sorry but you do need to get her to a vet quickly because the longer you leave it, the less chance they will be able to help her.
I hope I’m wrong that it’s a growth,it could just be an impacted hairball…I hope so…. but PLEASE do get her seen to.

  1. I just lost my cat with similar symptoms: decreased appetite, decreased energy, weight loss, intermittently labored breathing. The vet said that she had an elevated temperature, recommended and gave an antibiotic injection, but had nothing else to offer. After that she slowly declined over a two month period, until the past few days when she would barely move. She would put her paw in the water dish and then lap a little, but mostly she just lay still. She did not seem to be in pain.

    I did not take her back to the vet because when she was there before, he tried to draw blood, and when she became very agitated he said “she might be dying” — in other, words, a last flare of energy before actually dying right then and there. She hated to be put in the cat carrier, and given that he hadn’t given much hope, it seemed to me that it would be both uncomfortable and risky to bring her in. Now, I’m wondering if that was the right decision.

    When I got my cat she came from a shelter, so I don’t know her exact age, but she was 16 or 17 years old, with cataracts, so she couldn’t see well, and didn’t seem to hear well either. Last summer she had “a virus” according to the vet. He did blood work then, said that he kidneys were fine, no sign of cancer, and predicted that she would recover, which she did. I have some suspicion that she might have had Covid.

    So, she was old and tired and frail, and she breathed her last very quietly while I was stroking and talking with her.

    I hope that anyone with a younger cat with these symptoms will consult with the veterinarian, but I’d be interested in hearing of anyone with an elderly cat having these symptoms and recovering.

  2. Hey my kitten is of 4 months she have a noisy breathing and loosing weight day by day and her nose is always wet… please help me in knowing if she is having some problem

    1. Hi, there is only one thing that you must do immediately and that is take your kitten to a veterinarian. I’m sorry if you might find that something which is too expensive to contemplate. But it is the only way forward. Kittens are very vulnerable. They can die quite easily and clearly your kitten requires veterinary treatment as a matter of urgency. I cannot diagnose the illness because I am neither a veterinarian nor do I have all the facts to hand to make a diagnosis. I wish you the very best of luck and the same goes for your kitten.

  3. I have concerns about my cat. She is only 10 months, her mother and her became sick out of nowhere, the mother has gotten better, however my cat hasnt. My cat started improving for 2 days and then got worse, she has been sick a little over a week now. We noticed she had lost a substantial amount of weight, she eats a good amount of food. But she used to be playful and now she is unresponsive when she is called, she doesn’t move unless she is moving to a new sleeping spot. And tonight i noticed that she is breathing weird. It seems as if she is panting like she ran alot but has not moved in hours, also she makes wheezing noises every breath she takes. Can someone please tell me what’s wrong with my cat, i am getting worried.

    1. Chystal, thanks for visiting. My impression is that your cat is seriously ill and needs urgent veterinary attention. You won’t be able to home diagnose and treat her I am afraid. Sorry I can’t be of more help.

    2. Chrystal…
      RUN, RUN, RUN to your nearest vet clinic now!
      I could give you many reasons for her symptoms; but, ALL of them would require that you take her to a vet.
      Forget any costs. Most clinics will work with you on a payment plan.
      Your cat is very much in danger of dying right now.
      What you are describing is near-death behavior.

  4. Well, my cat, who is 13 I believe is going thru the same thing. She wont eat anything but tuna, and I mix some powedered amoxicillan in with it. I dont know if she will get better, she is rather old… but its so hard watching her. Our dog died 6 mo ago from cancer, so I feel like I just went thru all of this. Losing a pet is awful. They really do become part of the family… It s too bad they have shorter lifespans. Watching them suffer, and not really knowing how to help because they cant speak is one of the worst parts. All I can do is just be there for her.
