The Wild Cats

These three wild cats are living in the neighbourhood at my mamas house.

Mama and Brito are feeding them many times a day. 

They haven´t got any names so far, but I have heard Mam and Brito taking about

them saying "The ugly cat", "The grey cat" and "The loving cat".

I would really like to give them names but it´s not possible when I don´t know if they are females or males.

 Could be called Brownie?

Selma?

and Cariñita?
