Is my cranky cat normal?
I have a 2 year old cat, 4 yr old and 9 year old- all indoors. These cats have lived together for over a year with rare "territorial" problems. There's also a calico stray I've been feeding for over a year, whom came inside on a daily basis through winter. She would hiss if one of mine even looked at her l and go about her business, finding a sleep spot and crashing out. Even with the hissing, everything was very calm for the 5 months this went on. She came inside yesterday for the first time in a week and my 9 year old attacked her. She slept outside and I let her in again about 10 minutes ago. I walked in on my 9 year old stalking/cornering her, moving slowly and about to attack, as if she were prey. It really upsets me! Why has this random aggression become so regular for Old Man?? He gets tons of playtime, food, attention (more than any of them, treats secretly given to him and 2 walks a day through the hiking trails. So he's not "jealous." Is it normal for Old Man to behave this way, randomly?
