I have three adult cats, all found as strays. The first two I found as kittens so they now behave just like regular domestic cats. The third one I found a year later as an adult. I have integrated her with the other two and there are almost no personality clashes, certainly nothing to cause any behavioural problems.
However, when I found her she was very malnourished and had two kittens of her own. I gave the kittens away but kept her. Over time she filled out but became overweight. I now monitor her food carefully and she is an appropriate weight for her size. The problem is that due to her background she thinks that food is always scarce and she thinks she's always hungry.
Ideally I'd like to be able to feed all three cats at the same time in one room without her weight increasing. If I do that at the moment she eats as much as she can and stops the other two from eating until she's finished. The other two will eat out of one bowl at the same time. If I feed them in separate bowls at the same time she wolfs down her food and then eats the other cats' food before they've finished.
What can I do to reduce her food anxiety while keeping her weight under control?
