Possible urinary tract?

I have rag doll/ Siamese make cat called jinx he is the most love able Cato me only he doesn't like any one else going near him or feeding him nothing he particularly doesn't like males I've had him since he was a tiny kitten so I don't think he was ever abused. I have noticed tonight he has done a wee on my bed, this is very unusual for him and I noticed it was bright red. Could this be signs of a urinary tract infection? I have booked him in for the vets tomorrow just trying to figure out what I might be in for.

The blood in his urine is definitely a sign of an UTI/crystals. If this is what it is it's quite treatable and the vet will most likely prescribe a special food and give antibiotics.
My cat had blood in his pee a couple of times when he was getting recurring urinary crystals. It's been quite a few years now since he's had any problems though.

That's reassuring thank you for a reply, I can sometimes get quite worked up and upset when it comes to my animals. You have Been a big help!
