we have strays, cats and dogs. my brother brings them home on their verge of dying - some just wander in. everyone is immediately taken for shots and then neutered. they all have some type of issues, mostly i think they stay in survival mode. they all want exclusive attention, they dont trust us to know we wont hurt them, they miss something where they were from, they all want tons of food and try to eat each others before their own. each trys to run all the others off. some make very close friendships as groups of 2 and 3. the biggest thing ive learned is never let them be together, even if they seem ok w/ each other, unless they are the same size - at least until they display a real attachment. just tolerating each other isnt enough. share t
