I have 4 cats 1.) Med/ long hair black female ( Midnight about 2years old- been fixed) and 2 grey tiger ( Rigby same age as Midnight, Tyge about 6-8 months old) and Sparta (about 2 years old). Sparta is the one I am not able to figure out the breed. I've seen pics of hybrid bobcat kittens but his tail isn't bobbed, it's the regular length of a domesticated house cat. He has the coloring of a hybrid bobcat and is shorter than the other 3 though plus he likes to be outside where the other 3 don't want no part of going outside. When he wants to go out he goes to the door, meows then when he wants back in he comes back to the door and meows. When he is inside, he is mostly by my side so my family calls me, " His adopted human". They aren't really my cats, they belong to a family member who stays with me. Another thing I have noticed is Sparta has a black spot on the top of the inside of his mouth where the other 3 don't. Has anybody seen a breed that has the black spot on the inside of a cat's mouth or know what kind of breed Sparta is just from the description of him?
