hello I am hoping someone could tell me whether I should seperate my 11 week old Tabitha with our newest 8 week old kitten Sapphire or just let them sort it out, although they are only just 3 weeks different in age Tabs is double the size of little Saffy and Tabitha is being extremely rough she will not leave Saffy alone at all she is constantly pinning her down and biting her hissing ect and Sapphire is very vocal and squeals and meaows out loud as in pain. we brought sapphire, who is a small russian blue cross burmese breed, home 24 hours ago and let our 11 week old sniff through the carrier for a while and then was seperated over night last night, I introduced them today and its been constant following her around and pouncing on her. Are they Ok and shall I leave them or keep them apart longer??? heres some pics of Tabitha and Sapphire and you can Tabs is quite a bit bigger
