A Tubular Coprophagy-Preventing Cage for the Rat1

V. Chalam Metta2, Louis Nash and B. Connor Johnson

Division of Animal Nutrition, University of Illinois, Urbana, Illinois

Tubular-type cages designed to prevent coprophagy in the rat are described. The cages are made with half-inch wire mesh and are about 7 to 12 inches square, with an overhang for the feed cup. The rats seem to be comfortable in these cages, eat well and grow satisfactorily (5.7 gm/day).

The cages are completely effective in preventing coprophagy by both male and female rats and permit simple measurement of the amount of coprophagy practiced by rats housed in regular cages.

1 These studies were supported in part under contract no. DA-49-007-MD 544, with the Surgeon General's Office, U. S. Army.

2 Present Address: Nutrition Research Laboratories, Hyderabad, India.

Manuscript received 13 March 1961.
