We have one that talks to us all the time when she wants attention or outside. It sound like she is saying out when she wants outside and she will gripe at you if you do not let her out.

ONe of my kitties thinks her throat has been cut if the biscuit bowl is empty...and she really yells at you and screws her face up in the process. The other purrs like a chainsaw, and drools at the same time, so when patting him, its always handy to have a tissue to wipe his chin with!

My dogs and my cat burble in their sleep. The cat also does an "urr" and an "eh, eh!"

The urr is the noise he normally makes to announce movements such as "I'm jumping on the table now!" The eh, eh is the noise he makes while watching birds (and twitching his whiskers).

I used to have a cat who growled in her sleep. Sounded just like the Doberman.

Otherwise, my cat just walks around saying, "NO!!!" It's the Siamese.

"Are you a good kitty?"
"NO!!!"
"Do you love me, kitty?"
"NO!!!"
"Is world peace attainable, kitty?"
"NO!!!"

He's pretty smart.

Years ago I had a long haired cat that used to snore. One night he was sleeping on the floor at the foot of the bed and woke me up. Didn't realise how loudly he was snoring until I was asked by the neighbour in the flat above if I had had my friend stay over. The cat had woken her too!
