Has he been to the vet recently? If there is an underlying health issue, this can cause your cat to be in pain and can cause him to lash out.

This happens a lot, for instance, in older cats that have been declawed, because it causes arthritis. Obviously this isn’t the particular case with your cat, but he may be in some kind of discomfort due to a different health issue.

Also, cats can tend to get overstimulated. Pay attention to his tail when you’re petting him; the tail says it all.

If he puts his ears back, or you start to see his tail lashing back and forth, even if he is purring or seems to be snuggly, that’s a good indication that he has had just about enough and that it’s time to just let him do his thing.

ETA: How ofted do you spend time playing with him, and for how long? My cat will do this occasionally if he has been left alone or hasn’t been played with all day, because he’s trying to play with us like he’d wrestle with one of his littermates as a kitten.

I’d ask your vet about feliway?


My sister had just this skitzo cat, I mean he was just MEAN all the time and beat up the older cat often enough my sister had to get him stitches, would attack her and other people randomly.

Her vet said he was just a mean cat. He is perfectly healthy, just mean. 

My sister was about to loose her mind. she tried feliway as a last resort. And it’s worked so well. He’s a fat happy sweet cat now.

Ask your vet, and give it a try.

My dad’s cat is a maine coon about the same age, and will be “agressive” with my dad (leaping, clawing, gnawing) when he needs to play. They play fight for a few minutes every day (my dad wore a gardening glove until the cat learned not to draw blood). 

It’s easy to tell this agressive play from the cat’s fight-or-flight behaviour, because he will hiss,  lay back his ears, and lash his tail if he actually feels threatened.

I coulldn’t tell from your post, is your cat fixed? I’ve heard that unfixed males can be just plain mean.

Sounds like the in-laws siamese!  They have two of them, but the one male is extremely aggressive.  He will also attack the other male out of nowhere.  We just wrote it off as that’s his personality.

I would speak to a vet if you are concerned.  You may be able to find out more information.

@crystalrae:  I had a cat like that once…it was just his personality. He even got red-flagged at our vet because he was super agressive and bit the vet (she was fine, she called him a big grumpy sweetheart and just kept petting him. What an animal person she is!). 

I agree that you should get him checked out to make sure he is in good health and isn’t acting out in pain. But, it may just be that he is an agressive dirtbag (lol).

Our cat did grow out of it somewhat as he got older, and became quite cuddly – for him.

Have you taken him to the vet? If cats are aggressive it normally means that they’re in pan

Because he is a cat!

Haha…only kidding. You can ask your vet, but it is probably something that is going to have to take a lot of patience and understanding to deal with. Is he intact? Does he have toys and a place for himself? Are you playing rough with him sometimes? Cats can be pretty particular about things.

Seconding rachelmichelle, cats can get a bit worked up if you aren’t playing with them enough, especially indoor cats. We are lucky enough to live in a place wiith no real threats for outdoor cats, so we have indoor/outdoor cats and they still get a bit nutsy if we don’t throw a ball around for them in the evening. Some cats are cool with chilling around the house most of the time, but others (esp younger boy cats) need a bit more stimulation.

Do you play with him until he’s panting and completely worn out?

That would probably help, because he would get worn out.  It’s an option to try, just to see if it helps.  It’s something that Jackson Galaxy suggests for cats have a lot of play aggression.  On the other hand, there are some cats that actually do need medicine to help some issues.
