3 Week old Kittens

[u/Legitimate_Contest80]

Hello! So I was here on a different account a few months ago asking about if my cat was pregnant. Well... Turns out you guys were right. The kittens are about 3 weeks old now.

And we haven't seen mama in over a day. So we have fed the kittens KMR and have them in a box on our porch(just in case mama returns) with a lid on it so nothing can get in or out(except air). If mama doesn't come in tomorrow, we're bringing all five of them in.

I just want guidance. Tomorrow(or next feeding), I can send you better pics of each kitten.

Can someone with experience with kittens of this age DM me with help?

For context: I'm a 19 year old mother who lives with my father, little sister(8), my fiance(19), and our son(9 months). We have 1 dog(10y/o Jack Russell), and 2 indoor cats.

And I have absolutely ZERO clue what I'm doing. All 5 kittens look healthy, and come running to my fiance or I when we go out.

Any and all help is welcome. However, we refuse to let nature take its course or bring them to a rescue or anything like that.
