We're keeping him.
We weren't planning on keeping him, but after I finally got through to a human from the RSPCA and they said someone would come round to pick him up, we started to pine. We discussed it a lot, nearly cried a couple of times and eventually came to the conclusion that, as long as he and Jelli can get along, then we can keep him.
The lady from the RSPCA who turned up with a cage 10 minutes later wasn't too leased about that as she'd been travelling for two hours to get here, but never mind. She gave us a voucher to get him neutered and some flea spray because he's infested with them (you can see them running all about his skin, his fur is so thin in places) and left us to get on with it.
We're not using the flea spray though, because it's Hartz and I'd sooner get fleas myself than risk that on a cat (why? Look
here). Personally, I'm horrified that someone like the RSPCA would offer Hartz as a treatment, even if it was the only one she had in the van.
So now we have to work at getting him and Jelli to get on (the RSPCA lady told us to just let them "get on with it", which again doesn't seem like the most professional of advice) and also work out how we're getting him to the vet's when he needs to go. The moment Nick's wages come through we're getting some Bob Martin stuff to treat his fleas, and proper food and water bowls, as he's currently using breakfast bowls. I've also got to work out how to clean him properly - I'm thinking a wet facecloth and scissors are going to have to be the main things now.
We now have two cats. The landlord is going to flip...
