I have to give you a lot of credit to come onto a pet loving forum to seek advice

I have to agree 100% with BenMax. My hubby did not ever want cats as he is allergic and I thought I could live with that, but it turns out I couldn't. He compromised with me, even to the point of allowing the cats on the bed unless they have their tail in his mouth. If he didn't, I don't think we would be together today, I would have been too bitter. However, as it turns out, our cats have worked his way into his heart. He loves them all and they love him. Once you've opened your heart and experienced the unconditional love and 110% forgiveness that they give it is so hard to give up. It is truly amazing. Such traits are rarely seen in humans.
I hope you get to experience this love with his pets.
It will be easy to train the dogs to sleep on the floor, not so easy for cats. Good luck.
