Cat went after the dog
Tonight my dad fell out of a chair and startled the room, cat, dogs, humans. Then our Shipoo Punkin started barking and was agitated. Dustin started to hiss at him and when Punkin came by Dustin went after him and slapped him on the backside and chased him on the sofa where my mom blocked Dustin from getting to Punkin. I grabbed Dustin by the scruff of the neck and slipped a hand under his belly where he could not scratch at me, he was hissing at me very annoyed. His tail was also all puffed out. I put him in my bedroom for a bit and let him out when it was calm but he looked at Punkin and my mom started to get scared. She doesn't know how to handle a cat fight so I gave her a can of air that usually scares off Dustin. But now she's afraid he'll go after Punkin at anytime. I think it was the fright of my dad falling down right beside him and the ensuing chaos put out by the dogs that set him off but he's never behaved this way before, except for the incident with Muffin last week (I posted here about that).
I know cats will fight for their position but with the dog? Plus Dustin didn't go after Peanut even though she was barking, Punkin and my mom both seem to have anxiety. He never really liked Punkin's energy and he usually will hiss or swat with a closed paw and run off if the dog is bothering him (yet you can find all pets sleeping on the bed so he does tolerate Punkin) but this was an aggressive attack on Punkin and I'm concerned why he'd become physical now? I've had him since summer of 2008 and even when he's at the vet and being very vocal that he is not happy with what's going on, he's never lashed out at me or the vet.
I'd appreciate some advice on how to reassure my mother. I just started college yesterday and I'll be away for part of the day and I am concerned that something might happen when I'm gone and she'll not be able to cope with it. I gave her a can of compressed air but she says she'd never think to use it in a moment of panic. Should I take Dustin to the vet to see if anything is bothering him? I've been very pleased that neither of my cats claw at the furniture despite both having their claws and am concerned that I might have to have him de-clawed to protect the puppies.
