heeeeeelp! ive been feedin a stray cat for about 5 years now,recebtly he arrived badly injured,it looked like a burst absess on his face.it took me weeks of phonin around to finally get some help for him for free,finally a local vets funded by the rspca would see him,he was taken in,castrated,bathed,wound cleaned up and kept in for 2 weeks! i collected him and brought him home just yesterday in hope he'd stay,which he did for the day until the evenin,he wandered off out like he used to an stil has not came back,its been a whole nite an mornin now an im worried not to mention worried about the still not completely healed wound on his face thats open to dirt an everythin else.he did used to just turn up when he felt like it,sometimes days apart but now after all this why does he not want more for himself? am in a complete dilemma what to do next,heeeelllp??
