Yeh Holly's four and a half months now, I believe females can be spayed as early as three and a half. Rabbits is young though considering how short their lifespan is in the wild-- and omg I was at the chain petstore yesterday and the label on the rabbit tanks said lifespan was 4-6 years. I was like "WHAT? A well cared for rabbit can live over 10 years!" But then they also had them on a food mix that had a pile of seeds and shit in it. Rabbits and guinea pigs do not have the same dietary requirements, guise. Rabbits are lagomorphs. They don't eat seeds.

My guideline is basically that anything that's been prettified to appeal to humans probably isn't that great for the animals.
