"Bowl" - what is it, definition of the term
A rounded vessel, commonly fabricated from ceramic, plastic, or metal, functions as a receptacle for liquids or solids; in laboratory and pet‑care environments it provides the principal container for delivering food and water to small rodents such as rats and mice.
Detailed information
A shallow, round receptacle designed for providing food or water to small rodents such as rats and mice is a fundamental accessory in laboratory and pet‑keeping environments. The device typically rests on the cage floor and offers a stable surface for the animals to access nutrition without contamination of bedding.
Materials commonly employed include stainless steel, high‑density polyethylene, and glazed ceramic. Stainless steel provides superior durability, resistance to gnawing, and ease of sterilization. Polyethylene offers lightweight construction and reduced breakage risk, while ceramic variants deliver aesthetic appeal and excellent heat retention for warm food items.
Size guidelines recommend a capacity of 30–50 ml for mice and 80–120 ml for rats, ensuring sufficient volume for daily consumption while minimizing spillage. The diameter should allow the animal to reach the contents without excessive stretching; typical dimensions are 5 cm for mice and 8–10 cm for rats.
Key design features:
- Anti‑slip base or rubberized foot to prevent displacement during vigorous activity.
- Rounded edges to eliminate injury risk.
- Absence of lead‑based glazes or plastics containing BPA.
- Compatibility with standard cage dimensions to avoid obstruction of other equipment.
Placement within the enclosure should consider proximity to nesting material and ventilation, avoiding direct exposure to sunlight or heat sources that could elevate water temperature. The receptacle must be positioned on a level surface to facilitate even distribution of contents.
Maintenance protocols require daily removal of residual food, followed by thorough washing with mild detergent and hot water. Weekly sterilization using an autoclave or chemical disinfectant is advisable for metal and ceramic models; plastic units should be inspected for cracks before each cleaning cycle.
Safety considerations include regular inspection for wear, especially in chew‑prone environments, and replacement of any component exhibiting sharp fragments or degradation. Integration with enrichment devices—such as foraging tubes or puzzle feeders—can enhance natural foraging behavior while maintaining hygienic standards.
