Well I wasn't sure what he was so I assumed calico because the previous owner said the mother cat was calico. Now I'm thinking my cat is a tabby based on what everyone is saying.
Thank you so much for your response! Also, I got my cat neutered a month ago so he is a male. Although he did have unilateral cryptorchidism. It makes me feel special that male calico cats are rare though!!
The previous owner said that his mother was calico and the father was an all black cat. However, I'm not really sure. Can someone please help in identifying my cat? Thank you.
