Hi my cat Daisy had 4 beautiful kittens 4 weeks ago, when shen had them she went super thin as they do , but now 4 weeks on she looks pregnant again,she is not huge but definatley bigger. She was a very petit cat before she was pregant, she has been out but only for half an hour at a time but didnt think she could get pregnant that soon after birth?Could it be she may just be filling out? She does eat alot!! Thanks for any advice on this .
