I don't blame your husband at all for not wanting to keep her(?). 5 is alot.
The thought crossed my mind, but I do want to get another dog/puppy sometime. Maybe not this fall maybe next spring, it just depends when the right one comes my way, that is the way it was with Shai. I am sure my parents don't want me to, cuz it would be the same thing all over again. My house is too empty without the big goof running thru it. I remember all the times I took her to my parents house and the great fun was "running" running her up and down the steps. I would get to laughing so hard I would almost have to pee!!! I'm sorry to digress, this wasn't about the precios kitty.
Jessica, maybe if it isn't sick, you can put an ad up at the local grocery store or try www.animalhome.com (I think)
Good luck!!
