I can only think he might be stressed because I recently cat sit another cat, or that my sisters cat passed. He eats and drinks regularly, and I clean his litter regularly, but he’s increasingly clingy and has peed and pooped on my bed more than once.

I have no money to take him to a vet at the moment, but what could the issues be? How do I fix it? I’m worried about him, I don’t want to lose him but I don’t know what to do.
