If you have a cat flap (cat door) and keep cats it is likely that you are feeding your neighbour’s cat or a stray cat or a cat that lives four blocks away, particularly if your cat food is better than the average in the neighbourhood.
I have had three stray or time share cats eating out of my cats’ food bowls.
I put a bit of food down in the evening. Invariably a neighbor’s cat comes in during the night and eats it. My elderly lady cat then cries out for food…at three in the morning. I leave a bit of dry for her but she has got picky and only eats best wet.
If you are feeding your neighbor’s cat and a stray cat it can get expensive. I buy cat food in bulk online! A huge pile of it is delivered and stored away. It lasts about a week…! No just kidding but it goes down pretty quickly.
The thing is that the responsible cat keeper supports the irresponsible cat owner. They lean on us and it is irritating. When you talk to an irresponsible cat owner about their bad habits and try to get them to improve so they stop leaning on you to feed their cat, the slam the door on you.
In the USA cat doors are large allowing a dog to get through. Maybe you are feeding wildlife and dogs as well as your cat?
Do you feed your neighbor’s cat – either by choice or because you have no choice?!
