Can hamsters sleep with a blanket?

Some bunnies do sleep with blankets.

Beware of the dangers though: Bunnies can nibble holes in blankets and get their feet stuck in the holes. When a bunny gets trapped they can panic, causing injury and death! Another risk is that the bunny could eat some of the blanket, which could lead to serious illness, and even death (GI stasis). So, you have to consider the risks!

As cute as a bunny with a blanket may seem it is probably not worth the risk, and the bunny would most likely prefer a nice bed of hay anyway! Other safe things your bunny can sleep on are grass mats (untreated, completely natural), and cardboard (plain cardboard, unbleached, minimal colours, no glossy bits, no tape or staples).

If your rabbit has a blanket, you should check it every day for signs of nibbling and if you ever see any, take it away.
