Anecdotal evidence:

3 months old

1.5 years old (glorious winter coat)

The fluffy tail and especially ears remind me of my two cats, who started out with medium-ish fur and got considerably fluffier as they grew up. I don’t think there’s a way to tell for sure except waiting, but my guess is it will grow into the ear fluff rather than out of it :)

I would assume the worst and get both you and kitty used to brushing and cutting/shaving them. It youre unlucky the cat will have the kind of fur that matts often, getting real painful tangles in the pits and groins, not to mention poop getting stuck. If so you need to brush frequently to minimise the need to cut. Grooming isn’t cheap, but it’s possible to do at home and good to have trained for it before you need it. Some cats pretty much needs shaved pits lol.

They have very stretchy skin, so do just go hacking away blindly. Check out tutorials and as the vet or vet assistants to show you on your next visit.

If you’re lucky they’ll have more or less tangle free fur, but as long as it’s long, it’s good that you’re both used to you fixing it, because it will be needed someday.

Based on the tail alone, I’m fairly confident you have a long-hair cat.

You have to pet them to make sure, sorry

omg. their eyes are gorgeous!

Gorgeous kitty!! Is s/he a Turkish Van? Awesome 😍

Wait.

Generally the ear tuffs and paw hair that will give some insight.

When they puke it up.

Don’t shave your kitty

What a beautiful kitten! With such a fluffy tail, it seems likely he/she will stay somewhat fluffy. Ours just got thicker fur as she got older. Have you asked your vet?

The only way to know for certain is by documenting thoroughly, by which I mean to say we want you to post regular pictures of the cat.

It’s all genetics, so there’s no way to know in the same way you can’t look at a 5-year-old boy and know if he’s going to go bald at 50. Just love your kitten regardless.

Have you tried asking it?
