I COULD have voted 'vaccinated rabbit with kidney failure' but I haven't because I think this would be misleading.
I got an unvaccinated rabbit from a rescue. The rescue doesn't vaccinate and she'd been there about a year, I think, so she had not been vaccinated for at least that time. As soon as I got her I noticed that she was a very thirsty rabbit, but didn't know enough to know that this indicated kidney problems (I did take her to the vet but he didn't check for that either). All my rabbits are vaccinated, so she got vaccinated pretty quickly, and a few years later the kidney problem was diagnosed, and a few months after that she died from it. I am writing this because I think that the form of the questionnaire could skew results - it is clear to me now that Erbie had kidney problems from the time when I got her. However, like most people on this forum, I vaccinate my rabbits. Like most people on this forum I also am concerned about my rabbits and take them to the vet and want to know what is wrong with them, so I find out about kidney disease. I think that pretty well every rabbit on this forum who has a kidney problem will have been vaccinated, just as every rabbit on this forum with kidney problems will have been fed hay, but this doesn't show a connection between the kidney problem and the vaccination/hay.
Sorry if I am being mega-pedantic here, but I think that this shows the importance of controlled tests, where like is compared with like. It is a monomania of mine, hence the long reply. I get really fed up of surveys that say things like (I have read this recently in New Scientist, no less) 'women are better at finding their way round supermarkets, which shows that women are naturally the food-gatherers' (I would haver thought that it shows that women do more supermarket shopping....)
