...but it won't rise too far if you have rabbits. In fact with a couple of enthusiastic bunnies chomping away you could pretty much do away with the lawnmower and with the time you save mowing the lawn you could start teaching them to move their own run!
With the weather starting to warm up and the days getting longer, any young rabbits that you have kept inside over winter can be brought outside. Older rabbits will start to get urges of the sort rabbits are generally famous for. Pairs which could potentially breed will do so unless prevented by a trip to the vet. Two males or bucks as they're known may start to fight and if this gets serious you may have to separate them.
