Male cat humping other male cats

I have two male kittens and two male bigger cats. The bigger cats keep humping on the little ones and will not stop. What can do to keep this from happening. The poor little ones just can't seem to defend themselves. All are outside cats and right now are not neutered. I just feel sorry for the little ones and don't know what to do. Thanks for any help.

The first thing that comes to my mind is you should get the whole lot of them neutered! Especially if they are outside cats and could be impregnating your whole neighbourhood!

Sounds like the bigger ones are trying to assert dominance over the little ones.

I have a 9 month old male that was neutered when he was 4 1/2 months old and he is always trying to hump my abyssinian male cat...... All my cats are fixed and have been since they were kittens.... Goerge is just a sexual kind of guy....

I agree itâ€[emoji]8482[/emoji]s a dominance thing (nothing to do with sexual orientation). Neutering may stop it or may not. Please do get your cats neutered though for a whole lot of other good reasons.

I agree with the others, but have to add that my Isaac, likes to mount the others (no humping involved). With him I know it's a dominance thing.
