When I first got Louis, he had mucus and blood - lots of it. He was diagnosed with colitis and was given probiotics to add to his feed, anti b injection and tablets. It didn't quite stop til I changed his food to Nature Diet - cleared up in 2 days!!!
With George's other problems, it may not be this, so yes, a trip to the vet is on the cards. Good luck - hope George is better soon!
