This is a photo from their Instagram page of their two cats cuddling up to their dog. They are tabby cats. I have no idea how the cat adoptions took place. Although it is not clear that they are purebred cats I am told by the justjaredjr.com website that they have adopted a second Savannah cat. And previously I had speculated that they had adopted a Savannah cat (it appears that I was correct although justjaredjr.com may be taking their information from me!). It seems that they have adopted another whose name is Tuna. His mate (sibling?) is Sushi. The dog’s name is Oscar. In the video below they look more like Savannah kittens I have to say. The problem with identifying the cats is that Savannah cats are tabby cats and when young they can look like regular tabby cats in certain photos.
Here is a very short repeating video of the two Savannah cats:
