Well my pussy,keep it clean lol,is very very very untrainable,though havent spend that much time training,had a cat that fetched and retreived silver foil,but missy zebbi,doesnt seem to want to play the game lol!!!
My cat plays fetch with tinfoil! He has done ever since we got him, I never knew of a cat that did that before so we thought it was quite funny. Maybe he thinks he's a dog?
I don't know about actually training a cat, but they definitely can learn. My Frankie has epilepsy and needs a small tablet morning and evening. The first few times I had to physically sit him down, and then open his mouth. After about a week, I could say "sit Frankie, open your mouth Frankie", and he now responds to the spoken words with no problem at all. It is just as well, as he is only three and will be on this medication for the rest of his life.
