It's astonishing, I didn't think they could do that, but apparently they can.
One of the cats had seemed interested in fetch for several years but it never quite worked. I tried a bunch of different toys and finally found a plastic spring that she will fetch very well.
over there; bed; basket; lead; walk; wait at the door; go to [room]; go to [family member]; stay; stay on the path; paw; paws up; sit; lie down; heel; don't pull on the lead; no more poo poo; no more wee wee; this is the commute; up; where's your piggy?; treat?; buscuit?: up for a cuddle?; want to come up?; permission; okay; no; stop; this way; stay close; hungry for some food?; water?; down; don't lick; who did this?; come here; shall we go the pub; let's go;
and probably 5 or 6 more words/phrases. I don't include words like catch/fetch where accompanying action may trigger the response.
It's definitely not a three year old's grasp of language, but it's probably a point that a baby crosses somewhere between 9 and 15 months old.
My cats will regularly come when called, if they feel like it.
But... what's she going to do if you say fetch? If she wants to fetch, she'll bring you the toy and if she doesn't want to fetch, you telling her that you would like to isn't going to change her mind.
This is unique in my personal experience. I've haven't seen this in other cats.
Unlike dogs, cats aren’t seeking your approval. It is a different kind of relationship.
While my cat doesn't seek my approval, she is definitely highly food motivated to the point where she was faking wanting to go outside and thus put a harness on (which she does not enjoy) just for the treats she would get.
