My guys wear nail caps.
(Poe had an IV, which is why his legs are shaved in the pic)
If you want to use nail caps on a kitten, you have to start right now while he’s still young enough to think it’s just a weird human thing to be endured. You don’t want to wait until he’s big enough that you’re paying a vet to do it, which I only learned mine does when they asked if they’d done if for me. Start the prep tonight, even.
For the first week or so, you’re just going to play with his paws. Do it several times a day, for a couple minutes at a time. If he tolerates that well, tell him he’s a good good boy and compliment his cute little toes (no, seriously) so he begins to associate feet touching with praise and sitting on your lap.
Because he’s still a little guy, you don’t need to trim his claws yet before you put on the caps because you need enough surface area for the caps to stick to, and very young kittens don’t have long claws. Once his claws are no longer the needle sharp of babies, you will trim them before putting the caps on: you’ll know it’s time when kitten size is too small and you need to move up to small.
As he gets bigger he might grumble more about it sometimes (at a year they’re probably cooperative/resigned 75% of the time and annoyed 25% of the time), but being firm but gentle as you hold them on your lap like you would a human toddler - their back to your belly - usually does the trick. If he’s extra grumpy, give both of you a break before he gets really upset and come back to do the rest later. It’s far better to let him run off with only one paw done for the night than teach him that you’re going to be mean and force him after he’s told you he’s had enough.
My favorite brand is zetpo. They’re a softer vinyl than soft claws which makes them easier to put on but still last 4-6 weeks, come in way more colors, and half the cost. I believe that they call the kitten size XS, but I didn’t discover them until they’d aged up to small. FTR, they run slightly large so we’re on medium still for both cats.
When you glue your fingers together, and you will, pull them apart quickly. It doesn’t hurt to glue them together, but it is a glue very close in strength to super glue so you don’t want to have to tug on your skin more than you need to.
