i have two cats, both female, recently sterilised (4 weeks ago) they are 18 months and 6 months old (mother and daughter) we have just adopted a big 1 year old castrated ginger tom and things arent going too well. we left him in a room of his own for 2 days to settle in, then let him come into the living room where my ladies hang out. there was yowling, hissing, spitting from all parties and all three sit staring each other out. at night we split them up for fear of fighting. at first the couldnt be in the same room as each other but now they can sit at opposite ends of the room wihout chasing but theres still yowling hissing and crying from the older girl and the new tom. i know its still early on but is there anthing i can do to help them get along? also the new tom has still not eaten (its been 4 days) im getting a little worried.....is this normal from the 'stress' or should i be looking at a vet visit?
