I'd take him to meet some hairless cats ans maybe he would grow to tolerate or even like them. I'm trying to convince my partner that a snake would make a good pet as I have two bluetongues and a dog, but he is set on "it'll kill you in your sleep"
If you wanna hairless cat, get one. Your partner should understand you want one YOU would take care of it. Need to make decisions together and compromise about it, but I don't think your partner should mind THAT much if it means you being happy. Getting a hairless cat should not be the cause of a breakup and if your partner leaves you cuz of that then find a new partner who loves hairless cats.
Hairless cats are cute too!. My cousin had one and she was completely a lap cat. I love fluffy things, so is not my type, but my cousin loved her so much.
I do not know who owns the place or who pays the rent, if both are in the same conditions or not, but one thing is for sure: Animals and children are big responsabilities, both should agree in my opinion. If you can convince the reluctant part it would be perfect, rather than appearing one day with the kitty
Your partner will get used to the cat and start loving it in no-time.
When I first brought my boyfriend here he would make fun of my cat (he is flat-nosed) but now he wouldn't be without him. There'd be something wrong if a person would live with a cat for an amount of time without getting attached to it.
Talk it over with him again and say it'd be your cat. You buy it, you take care of it and you pay for it's expenses. I'm sure he'd get used to it in no way.
