so I have two cats, one that I have had since February this year (Saki), and the other since May of this year(Isis). When they play together, there's lot of chasing, and tackling, and smacking of heads, but when Isis gets cornered, say in a box, she hisses and hisses at Saki. Saki never tries to hit her or anything when she has Isis cornered, but still Isis hisses like she's really going to fight Saki. Saki has never done this when she has gotten cornered, or when she loses the games or wrestling matches, but Isis does. I don't get it. Maybe Isis is a sore loser? I have a feeling she was on "the streets" much longer than Saki, just based on her slight food aggression (it's gotten better over the months), and the scars on her ears. Saki has no such scarring anywhere on her gorgeous self, which leads me to believe that she wasn't a stray for very long, and had just gotten out of her original home before being picked up by the shelter. anyway, does anyone have any ideas as to why Isis hisses at Saki when cornered and Saki doesn't?
