we have a cat

Tabitha
We have an 8month old cat. She's great, except her hair and the smell of her liter is really getting under my skin. I told my husband I wanted to re-home her bc I don't want that smell or her hair around when baby arrives. At first he said okay and to go ahead and find her a home. Now he's refusing to let her go! What can I do?? He's totally flopped
