What breed are my two kittens?

I have two, almost one-year-old, kittens. Both female. I'm having trouble identifying their breed. We adopted them last summer from one of my mom's friends. She found them in a box in a গুল্ম near the elementary school. The mother had abandoned the litter I guess. She took them প্রথমপাতা and took care of them দিন and night.Their brothers and sisters where all adopted, and they were the only two left. We had no choice but to take both of them home. We named them Tommy and JJ after the cartoon, Tom and Jerry. We didn't know they were girls until a trip to the vet, and renamed them, Tommi and JeyJey. They are two peas in a pod; they can't be separated. They are sweet and playful.

Their পশম is black with dark grey stripes on the sides and legs. Their tummies are light grey. They have medium sized ears, brown eyes, long tails, and big paws. Tommi is very fluffy while Jey has short, shiny hair(see photo). Tommi has a sweet voice while Jey has a scratchy high one. They both are okay with wearing their collars, Tommi has red and Jey's is pink.

These two are odd, I hope someone can tell me what breed they are. I certainly can't tell. I've seen pictures of their other sister who was adopted দ্বারা another of mom's friends, and she looks just like them.

These two sleep a lot, even for cats... Most of the time, they like to sleep in the same spot and cuddle, aww!

I'd really like to hear what আপনি have to say, অথবা give a website that will help! It's the thought that counts. :,)
