Small Ceramic Dish www.petco.com - $2.99 (3.5") Product Review: The thoughtful styling of this functional ceramic dish makes it ideal for offering food and water to your small animal, reptile, or amphibian. The bowl features tall sides for generous portions, a high gloss finish for easy cleaning and great looks, and a heavyweight design that resists tipping. RattyRat's Review: This dish is horrible for everyday use, as it is way too small, but it works great for any rat(s) that is sick or injured and being kept in a hospital cage seperate from the rest. I always use it to give them their soy milk formula. It's the perfect size dish for sick rats.
