I can't describe the smell.
It was like medicine, something sweetish, mildew, and ammonia all mixed together. A nasty, chemically smell. And it permeated his whole house. Upstairs and down. You could even smell it outside, standing near the door. The rack still smells like that. The hides and water dishes did until I washed them. Even the snakes smelled faintly of it for a day or so. I've never smelled anything like that, and considering how it affected me, I can't imagine it being healthy for him or his animals.
