Both of my boys are very talkative, too. My ten year old dsh, Trixter (he has moo-cow patterned fur) has different sounding "words" for everything. When he is excited and playful he will do like a "prrrrrrrurrrrrow" thing, or if he is surprised or wanting something he has a VERY loud "MRRRROWWW!" with his deep little voice. lol When he has an upset tummy and gets sick he has this horrible, pitiful sounding meow before he throws up. It sounds like "muloddleloddleloddle" LOL, my poor baby.
My 2 year old Siamese mix talks constantly, too. Lots of purr sounding meows and high pitched vocalizing from him. He loves to play fetch, so he will drag a toy out of one of their toyboxes and bring it to you, all the while saying "rarrrrrrrrrrthhhhhowwww" or something to that effect. lol
I love their talking. Its precious. When I walk down the hall at night in the dark, Trixter will walk in front of me and talk the whole time, like he's leading me lol
And you should hear them when its time for food! lol, you'd think these boys are starving! Then I tell them "sit" and they both sit for their meals. Cats are so incredibly smart!
