As I said on the other thread, I would always go for insurance, as I do have a bad track record with cats and do recommend it, I pay around £13 a month per cat, and I know one person who adopted from me thought that was rather high.
Trigger, I find your post very interesting - I'm not quite sure of the link between our pets and children dying, even if I felt a need to give my money away rather than helping one of my cats, who are my family, it certainly wouldnt help any children, the only thing it would do is help another cat. Morally I dont feel bad about spending £1k in vets bills a year for the animal not to have very long, when it could help others, although there are certain routes my vet wouldnt take if I didn't have them insured.
