Thanks :-) yes I'm home all the time at the moment so I'm able to check on her frequently.
I was slightly concerned that I thought I could feel something a bit like a kitten low in her belly - towards her bits - but I have since read in other threads on here that this may just be her uterus...
So my cat gave birth to 1 kitten about midnight last night, we missed the birth and when she checked she had already cleaned the kitten. So I don't know what happened to the afterbirth, I'm hoping that it came out and she just ate it as I hate to think of it still being inside her.
I'm not sure...
