Theodore is the first cat I have ever had that talks all the time. Mostly it is trills. He doesn't meow a lot. When he is charged up and I am playing with him with a toy, he trills as he races to catch the toy. If the toy lands on him, Trill! He also coos and makes grunting noises. He always has a smile on my face when he talks. Such a cute little voice. Does your cat mostly meow or trill?
