Very cute kittens! The little guy on the left is a brown tabby. If it has narrow tabby stripes rather parallel to each other, it's a mackeral tabby. If it has large swirls of dark brown on lighter brown, it's a classic tabby. The other kitten would be called a grey tabby with white, same terms about which type of tabby apply. Good luck with your babies. Make sure they get all their series of shots, neutered, tested for Feline leukemia and FIV, etc. Make sure your home is kitten proofed. And most of all, love them and enjoy them for the next 16-20 years!
