We have a cat, who isn't ours really, we feed it etc, and it is here most of the day. We are not sure who he belongs to, but we have a freeling it is a neighbour, an old man who is unable to look after him properly, we think. He came to us looking very scruffy and skinny, and we have fed him up etc.
However, this morning, he did a poo in the house (he normally asks to go out - he is very well house trained, which makes us think he hasn't been stray for long) and there was a blob of fresh blood in the poo. What could it be? I am so upset about it. We can't really afford to take him to the vets, what should I do? I don't think we are eligable for PDSA/RSPCA as neither of us are on benefits.
