Oh, I understand, because my husband is the same way!!! This is why I have 4.....four cats!!!! All of them were strays, and we slowly acquired that many over the past 12 years and not all at once, but he falls madly in love with them and can't part from them either.
I gave in to our last little stray. She is the most perfect cat, adorable, total lap cat, doesn't scratch, uses the litter box, sleeps ALL night long....a dream cat. Would have been NO problem to find her a good home. Husband falls in love with her and says NO WAY, I can't part from her. Stephano, our little boy we found in the woods two years ago, same thing. He purred his way into all of our hearts, and at that point, I could have handled three. Yeah, I'm handling four, and it's all good now, because none of them are kittens, although Stephano was, and a wild man at that. I'd have gone insane with 5 kittens, uh-uh, no way! Yeah, that are just being kittens, totally normal, and it will get better. I suggest that if you are going to keep them, that during mealtimes, and maybe other times during the day, they are put up in a closed room, porch, somewhere, so that you can have some peace and quiet and the older kitties can have a break from the little monsters too, lol.
And my husband is all for keeping all of our cats, but then when it comes time to take them to the vet, he gets mad, and says "how did you spend that much money?" I just tell him, that's the way it is. If you are going to insist that we keep them all.....plus the one dog I have, who already has health issues and costs a fortune, then DO NOT get cheapo on me when it comes time that they need to go to the vet. Sorry buddy, but you don't get to pull that card on me, although he tries. Just remind your husband how much it costs, not only for the initial shots, spay/neuter, but as they get older, and if they get sick, hurt, need dental treatment, remind him that he better be prepared to be able to take them all to the vet. I need to constantly remind my husband of that.
If it were me, I would keep the two that you said you would keep, and find homes for the others. It does not mean that you don't love them, and yeah, you'll probably cry when they leave you. But take your time, find them not good homes, but the perfect homes, that will be their forever homes. Hopefully you can find friends and family, or friends of friends that you know are good to their animals, and they can be close, and you can keep in touch with them, maybe that will make hubby feel better.
My last stray, the perfect one, I tried and tried to get my sister in law to take her in, told her how perfect she was, but she would only take a declawed cat....not that she would declaw them, but she wanted one from a shelter that already was declawed. I warned her. Many of those declawed cats are thrown into shelters because they have litter box issues, and sure enough, hers did. Luckily, she is a good person and she is working with her and I think has it all under control, but she is now in love with my little girl that I tried so hard to get her to take, but she's ours now, forever
Good luck, however it works out. I say give those little babies a time out, or several, while you have some peace and quiet!
