Lixit Food Hopper Food Dispenser for Small Animals www.amazon.com - $5.99 Product Description: Lixit Food Hopper protects the health and vitality of small animals by dispensing clean, fresh food. Food dispensed in open crocks and bowls become contaminated by animal waste, urine, saliva, and airborne bacteria. The Food Hopper provides your pet with a protected supply of sanitary food that is up-off-the-floor and easy to consume. RattyRat's Review: This food hopper and others like it simply don't work. All rats will do with this type of device is remove all the food and burry it else where in the cage, where it will then get peed and pooped on. So these devices do not keep your rats food clean. Save your money and just buy a good bowl. Plus this particular hopper is cheaply made and attaches very poorly to the cage.
