I have the same problem with my 2 kittens. This is why i came here to see if i can find a sollution.

Ours are fed well - 3 times per day (they're still babies). But you cant literally feed them a full bowl, and if we are having our tea at the same time as soon as they are finished they run down stairs to try and pinch ours. And boy are they determined.

One of mine once balance on my head, then across my arm to pinch a doughnut lol!

For now we have to lock them out every time we eat, but we have the same issue. As they are so young anythin other that kitten food upsets there tummies a little but they are so good at sneaking into the kitchen and raiding anything that resembles food.

If anyone has any hints on how we can try and control this it would be greatly appreciated.

As amusing as it is to see them running around the dining room like its an easter egg hunt, I would prefer it if I was able to at least have a cup of tea and a biscuit without having to hide it from my cats lol
