Rescued these two about 4 months ago - absolutely no info. Assuming DSH, maybe Bombay? Definitely cat.

Rescued these adorable siblings but they had no info about age, breed, history, anything. I've put DSH on all insurance info (and it's probs close enough either way) but recently saw a cat show video of a Bombay and curious if these might have a bit in them? Sure people are sick of this question. Sorry! (Final photo of them 4 months ago and tiny)
