Many cages sold by pet stores are far too small for even a young rabbit. Keeping them in these tiny cages can cause a range of health problems, including obesity and stress if they’re not able to move around naturally. It could even lead to death because of the high stress level.
It’s also cruel. Rabbits are smart, social and highly curious, and they need to be able to explore their surroundings. They’re also incredibly active, and love to run and jump. The House Rabbit Society recommends that bunnies have access to a large exercise area at least five hours per day. The minimum space per small bunny in my country is 2 m², large bunny 3 m² (m² = square meters) .
And that’s the minimum. Many rabbit owners choose to let their bunnies to be freeroam in their room or house (after bunny proofing them, of course) just like a dog or cat would.
The WORST: Wire bottom cages
If you don’t know what those kinds of cages are I will include some pictures to show you. Basically these cages have wires as flooring and the bunny stands on it all the time. It harms their feet really bad. Some people use these cages because they are simply to lazy to litter train or to clean up after their rabbit because the poop and the pee just goes right through the wires. And those cages are mostly super tiny (mostly around 50 by 50 centimeters)
Not only has the bunny not enough space but he cant even properly walk around in the cage. Every step is causing pain. Imagine if you would stand on a wire barefoot all the time with all your weight pushing you down.
Wire bottom cages cause sore hocks wich is a really bad ilness for bunnies wich makes their feed inflamed they loose their fur and its really painfull for them. If left untreated, can cause a potentially fatal staph infection and cause death.
