I just adooted an obese cat from my neighbor and my cat isnt getting along with it My cat her name is saddie and she is a normal sized persian cat shes very nice and really isnt hostile to other cats or even dogs. But when I brought this obese cat over his name is tiger she wont stop attacking him! And I truly feel sorry for tiger cause hes so heavy he cant get away. Ive made sure he isnt eating her food or taking over her bed but she dosent like him. He however gets in alot of trouble like tipping over the food bag and will even scratch  the floor. What should I do? I am not for sure if hes marking his territory by trying to eat all the food or claw the floor or maybe its his size? Even though she does get along with bigger dogs I really dont know any ideas?
