If you are interested in "convincing" your hubby to allow a kitty into the house you may want to consider fostering.
This is my first experience with it. My motivation was a bit selfish. We lost Tazzy (our 20 yr old kitty) recently. We are NOT ready to have another kitty as part of our permanent family. I was afraid the loss would scar the kids and my husband into never wanting another cat. Fostering is perfect for us. We can give back and hopefully heal a bit too.
My husband wanted to be sure that I understood that he was deadset against this. I convinced him to try it once. He agreed but vowed not to be involved. Last night the oven timer went off and I couldn't take the kitten that I was holding with me to remove something from the oven could I? I quickly said, "Hold him for a quick second." I came back and found the kitten cuddled in the crook of his arm. I didn't say anything other than "Thank you" and took the kitty back.
The proof will be if he agrees to foster again.
