and why on earth bring snow indoors for your housebun? They are not children so won't feel they are missing anything..give them a cuddle and some greens instead!
Enrichment
Greens and cuddles are great but if there is never anything new or different for a rabbit to investigate it all gets a bit boring. You don't have to do it with snow but whilst it's available why not take advantage?
A house rabbit is not going to suffer ill effects from voluntarily spending five minutes digging in a bowl of snow indoors.
I also think new experiences that are positive help make a rabbit better adjusted so that when there are changes outside your control they are less stressed.
I certainly wouldn't put outside any rabbit that had health problems but five minutes outside for a healthy house rabbit is unlikely to cause harm (providing of course the area is rabbit proof). Scamp went out last year.. it's just not Scamp proof at the moment.
Likewise if your rabbits outdoors usually, running about for a bit on the snow isn't going to cause harm. Rabbits have impressive padding on their toes. Have a feel of your rabbits skin (you'll need to bury your fingers into their fur. They feel lovely and toasty even though your fingers are cold and numb. I'm having trouble keeping Gypsy in the aviary. She rattles the door if I close it behind me when I go out to check on her.. she wants out and about. We were chasing her around the garden at midnight the night before last cos she'd snuck out when I fed her :lol:
Again, I stress I'm talking about fit healthy, adult rabbits. If you've got elderly/frail rabbits then I agree it's different.
I think that you have to be careful you don't put so much energy into protecting them from physical harm you end up compromising their mental well being. A house rabbit might choke on a treat, get a foot caught in a toy or poke an eye on a willow ball... all small possibilities that you could prevent by removing all toys... just have nice safe, padded walls. You bun would be physically safe but soon start showing signs of mental stress.
It's your rabbit though, so your decision. Weigh up the pro's and cons, factor in your individual rabbit and make your own mind up
