Optimice Blockparty Auto-Water Cage Bottom for Rack-mounted Valves, Red

Environmental Enrichment combined with the Highest Mouse IVC Cage Density in the Industry

Optimice Blockparty Auto-Water Cage Bottom for Rack-mounted Valves, red polycarbonate, complete with two access points for connecting tubes

Blockparty allows up to 10 Optimice cages to connect to each other by use of horizontal connecting tubes. Simply plug in the Blockparty tube to connect any two adjacent cages. Rodent cage space can increase up to tenfold, allowing animals to move freely among the cages. Mice often compartmentalize any cage for day-to-day functions like playing, breeding, nesting, and eliminating urine and feces. When given a choice, mice have been known to preferentially nest in red cages, as compared to amber. When Blockparty tubes are removed, spring-loaded doors automatically close, reverting this lab mouse cage to a single unit.

Recommendations: Some Optimice/Optirat GenII Standard Bottle and Cap C79122P should be ordered if water bottle usage is also planned for some or all of the cages. We also recommend joining two cages together and placing enrichment devices such as running wheels in one cage and food and water in the other. Red or amber connecting tubes can be purchased. Blockparty provides welfare and enrichment by increasing cage complexity and living space.
