40 sheets of regular size, thin (ultra-thin?) pet sheets. Size: Approximately 33cm long and 45cm wide. Absorbent area: Approximately 27cm long and 39cm wide. Thickness: 0.5mm. Roughly half the size of a newspaper. ★Other sizes are also on sale★ #kumao'sPetSupplies ※These sheets are made overseas, so while the absorbent area will prevent leaks, they won't feel dry or smooth after absorbing liquid. There may be slight variations in specifications depending on the supply lot. Since dogs' daily urine output is said to be 24-41mL per 1kg of body weight, 2-3 times a day, these sheets can also be used for small dogs, cats, rabbits, and other small animals. They are a convenient size for use at the hospital, when going out, or when you want to lay down several sheets. They can also be used as sheets for reptile cages (like leopard geckos), for rodents like rabbits and guinea pigs, birdcages, and hamster cages. At home, I use them on the floor of my birdcage (after removing the droppings grid). They are also good to put down during bathing. Also for draining water from musical instruments (spit valves). (Water sheet, stage sheet, water drainage mat) They can be used for animals, and also for changing diapers for children. (Diaper changing sheet) The sheets will be placed in a zippered bag, compressed, and shipped via Yu-Packet. Thank you for your understanding that these are stored at home. We plan to sell nest boxes, bird tents, swings, and ladders in the future! #kumao'sShop #kumao'sBirdSupplies #kumao'sPetSupplies Tap the above hashtags and check "Show only items on sale" to see other products we are selling!
