Back when my DH and I co owned a pet shop, we had a large tokay get out. Man, after the lights were turned off, you could hear him bark when you were in the front. He usually stayed in the stock room, catching loose feeder mice and crickets. BTW, the store was 8,000 square feet. He was loud and mean! Nobody even attempted to catch him. I always wanted an albino pacman but hubby wouldnt let me. Got a red tail boa instead!
