if you want to keep them under control spay or nuter them
If they are trained and know each other for a long time.
i really dont know why cats like each other but what ever the reason its probably the same reason we do
Cats may recognize each other as siblings based on scent and familiarity, but they do not have a concept of family relationships like humans do.
It depends on the kind, and if they know each other for long for e.g.; you buy them as babies and they are habituated to each other, they may get along. There can be times when they fight, mostly for territory.
sometimes they might fear each other or the dog is scared or the cat will be scared we don't know how they communicate with each other but it all depends
All dogs.. the dogs just got to get to know each other with the cats. There are specific cases where a dog and cat becomes BFFL .
a cat do not smell another cats bums
Both of my cats are girls. They are sisters, though, but cats don't know if they're related to each other. So yes, it is perfectly okay to have two girl cats.
it's in eye contact does he look at you and smile that probaly means he likes you try to flirt with eyes
Get the cats and put them in different rooms. You then get a flea medicine and put it on them. Keep them in the rooms till you know there are no more fleas on them both and then you can put them back together.
They meow three times sctratch the dog and then eat a peice of water melon...i know alot of things...
to be honest i dont know but i would pay lots of attention to both cats to reduce the possibility of jelousy between the to cats
