This is a fluffy winter hammock M size for small animals♡ My friend's hamster always sleeps soundly in it *ˊᵕˋ* It's a hideaway-style house that can be attached inside a cage, and you can hang a hammock inside. By attaching the hammock, you can expand your pet's activity space. It can also be used as a place for your pet to climb. It can also be used as a sleeping bag, so hamsters, flying squirrels, sugar gliders, birds, reptiles, Roborovski hamsters, squirrels, rats, golden hamsters, guinea pigs, degus, and gerbils can sleep comfortably while gently swaying. The inside is fluffy and soft, with a good texture, and it also has a heat-retaining effect, so your pets and small animals can sleep peacefully even in the summer when the air conditioning is on. If it gets dirty, you can remove the hooks and wash it in the washing machine. Thank you for looking (⋆ᴗ͈ˬᴗ͈)”
