Biggles turned up in my garden 3 years ago in a really bad way and terrified of people. He must have been seriously beaten and abused - he had to have an eye removed and x-rays showed an airgun pellet lodged in his shoulder (see pics). He also has white stripes on one flank, due to previous serious injury.

It's been a long haul, but he's now the sweetest boy, who has recently taken another local feral (now another tame indoor cat here) under his wing. But Biggles has health problems, including terrible teeth and foul breath, arthritis in one hip, and now, possible kidney disease (that's my guess). He also has an intermittent morning breakfast vomiting problem (not hairballs - possibly bilious vomiting) and some warts - down to about 6 from about 100 when he first turned up.

He's not a young cat (age unknown), but he deserves a few more years, of happy life, after the truly horrible times he's been through. My other, young cat (another feral, who took up residence in my shed) is absolutely devoted to him. He follows Biggles everywhere 24/7 and cries if he can't find him. Biggles needs a vet visit and some tests but he's uninsurable (I tried) and the tests, teeth cleaning and anaesthesia will cost hundreds. Also, because he's so scared of anyone he doesn't know he needs a home vet visit to sedate him for transporting or examination, or to take blood.

Biggles has had a terrible time but now has a loving home and is a happy chappy, but he needs help that I simply can't pay for. For him, and for the sake of his young tabby BFF (see pic), please help me to get him the veterinary attention he needs! It will be hugely appreciated. I can't bear the thought of losing him because of the expense of vet help (PDSA is not a local option, even though I'm on a very low income); and the two-year-old tabby will be devastated without him (as will I...).

Costs breakdown - I'm expecting the total vet bill to be £550-700. I can cover the balance (with difficulty - but if ever a cat was worth it, he is).
