Initially he denied keeping animals on the premises but when we prevailedupon him to unlock the terrace, this is what we found: trays of mice were found strewn, some mice had died of cold (it was the month of December), others had eaten each other as no food or water had been given. In a tray under the water tank, a breeding rat had cannibalised her newborn babies and only the remnants could be seen. In another corner of the terrace was a bucket of stale water filled with frogs, half of which were found to have died. In other cages, rats and mice had not only died, but were left to rot Mr. Suri is a popular supplier and has sold animals to Delhi University colleges, Maulana Azad Medical College and All India Institute of Medical Sciences. For a consideration he can even supply cats, dogs and monkeys caught off the road. His frog suppliers bring frogs in gunny bags and earthen pots from Bulandshahr and Guwahati by train.
