[Fluffagrams]

I think it depends on the hamster and many of my Chinese Hamsters have had hammocks for years without there being any sign of chewing. A well made one has been designed to reduce the risks of chewing and I still have some of the Fuzzbutt Cage Conforts hammocks I bought several years ago.

If I give hammocks to my hamsters, I tend to be vigilant, checking for any sign of chewing on a daily basis and removing it if necessary but in most cases if I put some toilet tissue inside, they have been content to make a snuggly nest there without needing to chew the hammock itself.
