Is Cat Conjunctivitis Contagious To Dogs? — 12 Comments

  1. Thanks for the article and advice. The question came up last weekend when one kitten with conjunctivitis spread it like wildfire to the rest of the litter. They’re on meds now, but the question came up since one of the infected kittens is about to be adopted along with a Maltese mix dog. Shelter personnel are divided. Personally, I told the adopter that the kitten would have to be on meds for a few days before being adopted to be safe. I figure, why take chances?

    • I totaly agree – if it’s not a problem to wait a few days, then why not. You may as well. Funny how nobody really knows for sure.

    • Pleasure to try and help a fellow cat lover. It was a bit of a struggle producing this post! That tells you the information is not out there, which is surprising. Neither is it in the books I have.

      • Well, don’t feel bad. I’ve gotten conflicting answers from vets too! The general consensus seems to be to quarantine to err on the side of caution. Thanks everyone for your input. BTW – I totally convinced the adopters to wait when I told them that any sickness would be on their pocketbook since they’d have total disclosure. Considering vet costs these days, they opted to wait.

        • I find it a bit odd that more isn’t known about this. There are lots of families with cats and dogs. Herpes virus is common and so therefore will conjunctivitis. So where is the veterinary advice on transmission from cat to dog?

          • Therein lies the question, doesn’t it? The best I can find is that, generally speaking, the virus shouldn’t jump from cat to dog. The fine line seems to be if bodily fluids are exchanged (rough-house play/fight) causing cuts/scratches, etc.), there may be a chance of passing the virus. I’ve also been told it depends on the type of virus. In other words, I really don’t know anymore than when I started, but I think I’ll still err on the side of caution.

            • Couldn’t agree more. I think we can conclude that there is a chance of transmission either bacterially or as you say in the virus. Even a small chance means we should take steps to prevent transmission.

  2. It’s unusual for a cat to rub up against or cuddle a big dog – Marvin sounds like such a great boy – friendly 🙂 I wonder if Daisy is much taller so it just doesn’t reach her eyes? I wonder if it just happens that afterward Daisy didn’t happen to giver herself a clean or somehow get the bacteria up to her eye through some motion. Maybe even sleeping with her head on her leg where Marvin rubbed against.

    • Oh, Marvin is a cuddlier with Daisy. Nose to nose when Daisy is laying down. I’ll ask Michael to add a couple pictures here if he can. It was the nose rubs I was worried about, but no problems so far. Marvin is certainly unusual in this regard. It is as if they were old friends.

      • Oh….I must see these photos, dw. They are like old buddies. They really do like each other. This gives us an insight into the emotions of cats and dogs. They have more emotions than we recognise, I believe.

  3. Marvin’s first mis-adventure trip to the vet was mainly for conjunctivitis and his symptoms were as you discribed, a thick mucus yellow discharge from his eyes. The vet diagnosed feline herpes. Marvin rubs up against ‘his’ dog Daisy often. Fortunately she hasn’t shown any signs of problems. His episode lasted a week and he’s been fine since. I understand it can show up again at any time. Bummer.

    • Nice to hear that. First hand experience. On the basis that a bacterial infection causing conjunctivitis can be transmitted from cat to dog and human, it is still rare and difficult. There has to be direct contact and the infection has to get inside the individual. There are a few obstacles/barrriers there.
