I think she is kind of stuck on what to call Mouse breed wise lol
Ah, I see. Apparently when I was younger I told everyone my black cat was a Bombay.
I imagine this won't be any help, but here goes:
The coat color does not tell you what breed they are, just like many cat breeds have several different coat patterns but they are all the same breed (
like the Bengal). Any kitty that doesn't come from a breeder, where the cat's history can be traced back several generations, isn't really any breed at all. A "purebred", such as the Siamese, you can only get from breeders. A lot of people with a cats that
look like a Siamese tend to call their cat Siamese even though that is incorrect; just because you
look like something doesn't mean you are one. Purebred cats cost a lot of money. Breeders (should) try their best to keep their cats free of any genetic defects, like heart problems in the family, and they try and breed cats to look and act very similar in order to keep the breed's standard. Like how Siamese are known to meow.
Then there are coat colors, and any kitty can have a coat color that
looks like a certain breed, but that just means in its history somewhere there was a Siamese, or a cat that looked like one.
Both of your cats are called "domestic short haired" cats. That means they don't come from a breeder, they have a lot of random bloodlines in them, you can't trace back their history... and that they have short hair. Most people have domestic cats (domestic short hair/domestic medium hair/domestic long hair), even if they may look like a certain breed. Your kittens' coat colors are called "seal point" (err, or "chocolate point"... I'm not an expert, looking at the pads of their feel would tell you which, seal point have dark pads, chocolate points look lighter) and "calico", but those are not breeds... just like humans could have blond hair or darker skin, but just based on those facts does not mean we're only one race, we can have a people from different parts of the world in our family tree.
