My cat had 3 kittens , 2 died unfortunately because momma cat was not producing milk ,when I reliezed this I started feeding this last baby, momma cat cleans baby and makes it potty but the past few days momma cat keeps bringing the baby to me and leaving, I'm worried, I made a vet appointment , but I'm thinking she's expecting me to do all the work now since I'm feed it, or there is something wrong with the baby
