Thank you for like our products, the owner has two lovely pet rats and has always wanted more pet accessories to help them live better and provide as much joy as possible to their short lives, as they have brought me. Pet rats by nature like to climb and sleep in the high out, but rarely find a suitable summer pet hammock, summer use of ceramic beds completely non-absorbent, but also lead to small pets of urine stuck in the fur, both health and cleaning brought a lot of trouble, but padded thick hammock, and really not suitable for summer use, always worried about whether the pet will be because of the temperature of heat stroke.
