hello everyone, a little help needed please. having found a beautiful black and white kitten to complete our family around eight month ago i didnt think it would be so soon before we would be celebrating her having kittens lol

. during her first heat, my daughter let her out and guess what....now ive just spotted a swollen tummy!!!
i havnt had a cat since i was young and never experienced a cat pregnancy or litter. i havnt a clue what i should be doing, signs of labour or anything. so any advice would be much appreciated. i am also a little worried as my cat, Sapphy is quite a bit smaller that an average cat and im worried about the stress of labour on her.

she's like my own baby lol.
any help and advice would be great...if only to put my mind at rest. thanks in advance. take care everyone......Kate xx
