What an adorable little baby that is!!!! How could you not fall in love..... Sometimes I think husbands just don't get it???????? But my husband would say the same..... I think. You know that little kitty could have Coccida???? My little Chloe baby had that really bad when I first got her and her little bottom was very red and inflammed just like you mensioned. Does it have really runny poops??? I would guess yes if it is sticking to him. I actually had to give Chloe baths because being kittens they don't slow down long enough to clean and it keeps getting stuck in their fur. I am sure the bad diet would be part of the reason also. Thank you for taking care of this little guy!!!! YOU ARE A SAINT!!!!
