Hi,
just recently my male 3 year cat (George) ran away and came back 4 days later smelly like skunk. we have another cat which is a 3 year old female (Graycie). they are brother and sister. now when ever graycie sees george, she hisses and growles at him. before george ran away they used to be very friendly to each other and play fight alot. but now she wont even go near him. does anyone have any adivice. we think it may be because of the skunk smell but we arent sure.
