It's possibly to get quite a conversation going with Sirius, the gentleman cat, though admittedly only when he initiates it, and even then his topics tend to be food related. His main opening gambit is "Mwah??????" (going up at the end like an Australian), which means "Are you going to feed me now, else I shall fade away and collapse in front of your very eyes?", though there's also "Mwah???" - less urgent: "I realise that you're sitting in the study, blogging, but I'd prefer you to accompany me to the kitchen and add some jelly stuff to the perfectly good meat - from which I have licked the jelly - already in my plate."
Cassie, the lady feline, has really only one piece of verbal communication and that's "Aaaah!!!!", which means "Put me down AT ONCE!!!!."
Both cats' communications are perfectly effective.
However their lack of response to my chatting hasn't stopped me, this weekend, from narrating my actions to either cat ("Right, I'm going out into the garden now"... "I think I'll have some soup") and asking them questions ("What have I done with the keys?")
What do you think? Getting a bit senile? Or do you do it too? (I imagine people also talk to dogs.)
