I rescued these sisters two weeks ago when their owner moved and left them behind-their coloring is very unique. From best I can tell I would guess they are Siberian mixes? Can anyone tell me what each of their coloring would be called? Blueberry (Billie) is the more tabby looking kitten and Lily is the light Calico looking kitten. They have long hair and I am guessing around 5-6 months of age? I am actually afraid that the Calico might be pregnant but have no experience in cat pregnancy. We see the vet today so wish me luck that it’s not the case! Both girls have a spay appointment Thursday.
