Two mothers and two daughters go to a pet shop. They buy 3kittens. Each female gets her own cat. How is this possible?

One of the girls is named cat? I don't think that's it.

One of the gatos is pregnant lol?

The daughters are siamease twins

One of them already has a cat ? wait there buying gatinhos so they must all have gatos already?? idk

One of the daughters is also a mother? Or they buy a full grown cat along with the three kittens?

There are only three women! A grandma, a mum and a daughter. The grandmother is mother to the mum, and the mum is mother to the daughter. The mum is the daughter of the grandma and the daughter is the daughter of the mum. Does that make sense?

Grandmother, Mother, Daughter: Grandmother and mother are both mothers; Mother and daughter are both daughters. Idk, just guessing. =P This sounds right to meh though. :3

there was a grandmother, mother, and her daughter.
