Since Taz has been here Puff has been doing this cat call. Sounds like he's a female in heat. (Both cats neutered). Taz comes running to him and he stops. So is he just taking over a roll of big papa? I guess even though I'm not a novice cat owner (I've had quite a few over the 28 yrs of my life) some of their behavior still puzzles me. Especially when two is together. I normally just have one.
