I tell you what... in a week or so...Mommy will get into heat and will mate and get pregnant and birth kittensd.
When kittens turn 2 months she would leave them...they will be on their own.
Anyway... those kittens will get lost and will be in danger of street dog attacks. I kind of know this...
I am still a bit upset that I could not shelter rather did not shelter a young small cat roaming in the apartment, was not upto it, its gone.
But anyway... cats are the sweetest things ever. I hope you can adopt two kittens as pet or something.
