Savannah Super Cat
I think 4 days is too soon to let them interact. The minimum two week quarantine is recommended for good reason; for bonding with you, letting your first cat learn there is a new housemate, for observing any possible illnesses in the new kitty and letting him adjust to a new home.....and because these are both somewhat older kittens and your girl is a picky eater and tried to sneak attack him....I'd stick with keeping them separated. I know it's hard not to let them be together sooner, but in the long run you will be glad you did
