Do you have any pictures of your cat standing, taken from the side? In general, your cat appears to be a red tabby domestic longhair, but those legs appear to be quite short. It would be helpful to see the proportions of legs and body.
What a cutie! I would describe your cat as a red and white Domestic Longhair. They do seem to have short legs in the picture, so maybe they have some Munchkin in them. They also look like they have a fairly flat facial profile, so I think Persian ancestry is also a possibility, and that’s a breed that has shorter legs as well (but not as short as a Munchkin cat).
