100% Jute twine and burlap two-tone pet hammock would be a beautiful addition to any crabitat!  Useful for storing shells or creating a second level.  The burlap has less stretch than a fully crocheted hammock, so it makes a firmer net or platform.  Long ties included for easy suspension.  Jute is safe even if ingested by a hermit crab and is safe for other pets as well.  Pre-washed and treated with Himalayan pink salt to resist mold.  Very delicate edges (burlap is prone to raveling), so this should be cleaned by hand.  Biodegradable.
