Why do my cats sometimes get aggressive during play or lounging?

It could be that they are fighting for dominance, or they could be playing flighting with each other. Given that there is no aggression in the fighting (i.e. biting), it's more likely they are just playing with each other. It could also be that one gets annoyed at the other, they argue over it, and then get over it. It's natural for cats who live together to have incidents like this, and as along as there is no biting or aggression, it's not something to be too concerned over :-)

Great question! It sounds like Razi and Jinx are getting along well together if they are sleeping next to each other, grooming, and eating next to each other. It can be normal for cats to chase and wrestle, and sometimes bite each other. I would look at their body language as they are doing it. If their ears are back and their posture is tense, then this is fights. When cats are playing, they will be relaxed and and their ears will be forward. Keep in mind as well that it's normal for cats who live together to have the occasional fight. I have four cats, and while they get along really well with each other 90% of the time, they do have the occasional tiff with each other. Sometimes one really annoys one of the other cats, and that cat lets them know. Just like with humans, you are agin got have the occasional fight. They won't get along all of the time. I hope this helps :-)

This sounds like a typical play behavior. In general watch for signs that one cat is trying to avoid the other cat. Watch for the cats hissing at each other. Watch for any signs of intentional bites or scratches that leave marks. If the cats are willingly interacting and you don’t notice any hiding or avoidance behaviors, this is likely consensual play. You may also look into reading a few books about cat behavior as it is not only informative but also fun! I hope this helps.

It may be due to illness or injury. It can also be redirected (or displaced) aggression. This is when one cat is unable to directly respond to a perceived threat and "vents" on whoever is closest. This is usually an owner or another pet. Never handle or grab your cat if she is displaying aggressive tendencies. This can lead to a serious bite or scratch. Schedule an exam with your vet to rule out medical causes. If they are indoor cats, provide a ' cool down' period by separating them. Keep stray or strange cats away from windows or doors and out of your yard. Control what your cat sees by closing doors or drawing the blinds. Consider using pheromone products to decrease anxiety/stress level in the house. Search www.pet360.com for pheromone products.

Cats, like people , especially siblings, do get into tiffs at times and fur flies.....this is quite normal and nothing to worry about. I have 5 cats and one or another fights here and there and the next day you see them lying next to each other. Unless one mobs the other constantly, the occasional tiff is nothing to worry about

If only pets could talk! Cats can be very reactive and can also get frustrated easily. It’s possible they saw another cat out the window and are reacting. You may try to separate them for a few hours. Keep the environment calm and check on them frequently to make sure they are not agitated. You want want to close the blinds to block out any views of the other cat. If the behavior continues, have them examined by the veterinarian. I hope this helps and please feel free to post any additional questions.

It is OK behavior but not great. I am worried that this could escalate into a serious fight. I suggest you try using some Feliway diffusers in the house and do some environmental enrichment for them. Those two things should help.
