my new cat cookie was rescued last week as her previous owner did not want her because she was pregnant so i took her in and within 2 days we had 5 brand new kittens mum is doin well and so are the kittens all except one i feel she is not putting on weight like the others and she is quite small compared to the others i was wondering is there anything i should or shouldnt do as im quite new to the kitten side of cats any help and advice would be greatly appreciated
