Help me make this decision.
I've got 5 cats, 4 are my housecats (2 persians, 2 moggies) and 1 is a typical indoor/outdoor moggie that belongs to my brother.
My brothers moggie I agreed to look after when he had to move back in with parents for a while, that was 2 years ago, he has made no attempt to sort his life out and have her back or even pay me a penny for her upkeep, hes disinterested in his cat but forbade me to get rid of her.
I dont want to look after her anymore, she regularly brings home fleas, yesterday it was a tick, often she is dirty and has clearly been fighting, she is often unpleasant to my cats when indoors and sometimes attacks them (but loves the house humans). I've tried to train her to be an indoor cat but she wont have it, my old persian is allergic to fleas and i've got an 8 week old baby, I dont want her bringing in whatever with my baby here.
I've tried to rehome her with family/friends (parents dont "do" pets so thats a no) and offered to pay for everything for a while but got no where.
She is only 3 years old and would make someone a lovely pet, DH wants to keep her in case the sanctuary put her to sleep as they have so many to re-home, DM has insisted I get rid of her and is coming tomorrow to take her to a sanctuary, I dont know whether to let her or whether my DH is right, what do I do?
