my cat tc is very talkative, he chats to me when im in the bathroom, i leave the door open and he chats away to him, i ask him questions and he repllies to them - he also yowls when he wants to as well.
my other cat benson (who is now at Rainbow bridge) uses to chirrup when he talked, i must admit i do miss his chirrup but Tc is great, i love having a talkative cat - my non cat owning friends think im mad when i say he talks to me!!!
