Mine have been neutured (exceptions of the newbies) and mine have all been adopted through people not wanting them anymore and asking me if I will take them in, guess they know I am a soft touch! I currently have 4 bunnies and 6 guineapigs all from unwanted homes , all treated well, all given my time but I have to say their 'running costs' arent really that high but then niether are that of a dog or a cat, all my animals are registered with the vets and are given the appropriate treatments when needed so please dont assume I dont understand the costs of keeping animals.
I have been keeping rabbits for 16yrs so am pretty experianced, I was trying to get accross that to a new pet owner who wants a pet for their child or sometimes themselves the cost of adopting compared to the cost of buying privately can be a big difference in their eyes, if they've never owned a bun before they wont understand they need neturing or jabs etc so in their eyes its buy a rabbit for a tenner, stick it in a cheap hutch and feed it and stroke it, sadly these are probably the rabbits that will end up in a rescue center later in life!
