A question about pooping...

I know this may seem a silly question to some, but I am stumped...
Sibyl's kittens are now 11 days old and I have watched her stimulating their bums to make them go...my question is...I haven't actually seen any pee or poo. Could they be constipated or would mama just clean up after them that well?

Advice would be greatly appreciated as I am worried and can;t find any other info other than how to make them do it myself.

Don't be worried, mom is the pooper scooper. Female cats eat the waste, it is instinct, to keep the nest from smelling bad and attracting predators to her babies.

Kyla...believe me, you will miss these days when your kittens start pooping and mom doesn't clean it up.

Wow that is so interesting!! The things I learn on this site....

Makes you glad not to be a Momma cat, doesn't it! I've changed enough stinky diapers to be very happy to have used pampers and wet wipes rather than my tongue!
