wasnt sure how to title this
now the fleas are abating, sods law ive just noticed that spare cats bottom is very red, shes not keen at me having a close look but it looks sore and distended (sp) and theres a clump of black hair caught (shes black and white) shes not licking it alot or acting like shes in pain but she has been glued to my lap all weekend which is odd for her. vet immediately or tomorrow? i dont spend at lot of time examining her foo foo so im not sure if this is just a normal part of some sort of process? or haemoroids?
edited to add, the cats share litter facilities and ive not noticed anything odd, she seems to be cleaning as normal
