Rabbits are much different than dogs or cats. Especially around here, there is no over population in my area, in the shelter there are 2 rabbits that's it! maybe even one! not very many people abandon rabbits around here maybe the odd person but not MILLIONS AND BILLIONS per year! I actually saved another abandoned rabbit. Charlie who was a really friendly guy after of course Spice. I lured him into a cage with a peice of Spice's fur and he was caught, and the best part someone adopted him right away! She calls all the time to update us and how wonderful he is. Most rabbits around here are kept outdoors too, which I do. I don't see a problem with it, no rabbit I have ever known has died from freezing to death or heatstroke around here(baby bunnies of course but not full grown bunnies). My Aunt had some luck with her rabbits, I know a black one who still has the same home, and two does were put in the petstore and were gone the next week. The petstore up there has a vet working there! The only worst incident with loose rabbits was recently, my aunt gave away 7 babies and ChocolateChip( a BEAUTIFUL mini rex doe,Spice's full sister,gone to many different homes,including mine,my parents made me give her back ) and the people drove all the way out miles and miles away and dropped all the rabbits at the camp ground, some must have been found! Most likely ChocolateChip, she was a smart one. And the second worst was about 2 years ago when people got 2 Mini rex from my Aunt,ChocolateChip & Peter(both Spice's full sisters), they got a new rabbit from the petstore,ChocolateChip attacked her so they gave her back, then a few weeks later Muffin gave birth to 4 babies(Cinnamon came out of this litter<3), my best friend had both choosen and everything but we forgot to tell my aunt, then she gave them to those same people who gave ChocolateChip back, poor buns had to go live with a 3 year old, anyways, one morning they woke up and there was a whole in the ground and all the rabbits were gone and...never came back so everyone knows what that meant! I've only ever bred with success twice and have never had any problems. Everyday I go out and spend time with my rabbits,bring them in the house,put them on there harness which is risky and i'm not very keen on, there are many eagles up there since I live on a lake, I always have too look up at the sky every 5 seconds, I'd know if there was one my rabbits would get spooked.
