Monty has a weeping sore on his hind leg that won't heal. His leg was swollen, the vet drained some fluid off (lots of blood in it) but it filled up again within hours. We think he may have a tumour that has damaged a blood vessel. I've had Monty, a rescue guinea pig, for 5 years, so I realise he's no spring chicken. He's eating well so his quality of life is still good. A friend has heard that putting honey on the wound may help heal it. Can anyone advise please? We've got a super vet. We've tried 2 types of antibiotics. Many thanks.
