Despite the fact he is middle aged, despite the fact that he only has ONE EYE because he lost the other in a fight, despite the fact all the other cats round here are massive and he is not.
We're frequently at the vats for antibotics as he always has an infected bite. Can't get insurance as unemployed and I've used a lot of my savings already getting him treated - am eligible for assisted PDSA treatment but the centre is too far away 
He's got another bite inside his ear, it's infected. I can feel his glands are up. He is purring, eating, but shaking his head a lot. I've bathed it in a saline and draining it (GROSS
) - any more I can do or will it be another trip to the vets at nearly a hundred quid? He seems happy and he's had worse - how can I help him?
