So my boyfriend bought Lucky a new piece of furniture. He got it from PetSmart. I was reading the tag on it and it says it has "special PetSmart exclusive antimicrobial agent" and tells me to not use soap. Seeing that this piece IS from PetSmart, does anyone know if this "special agent" works? And if not, any suggestions on cleaning it? It's the big branch, and another question. I measured the distance between the highest branch and my repti-sun 10.0. It's around 6 inches. Is that ok? If not I'll move it around more, but he was up on it earlier snoozing on it.
