Chucky is an extremely loyal cat, and I love him with all of my heart. Jasper seems like a sweetheart. And when he hissed at Muffin, it reminded me of the times I would get new cats and he would hiss at them all. When Jasper makes it through, (I'm pretty hopeful for this cat. ;3) he'll get along with Muffin just fine. All cats do eventually.
Our cats seem like they're alike in many way. Chucky actually tackled the cat that attacked me. I'd shove her off and then I'd see his big fat body barrel into her. xD I was in pain and crying at the time, mainly because I was being clawed, but when I look back at it, I laugh. I still imagine his pudgy body just smashing her for a few seconds before my old cat (Her name was Sammy. We had to put her down because she had attacked my cousin too. D:) would shove him off and attack me again.
