I went to see a house recently, owned by a vet I think. In various places in the house were tanks of turtles, lizards and other reptiles. Also birds. Downstairs smelt a bit funky, then upstairs it was really strong, I think from the many heat lamps and animals. I couldn't stay up there for long it made me feel quite nauseous. Obviously the estate agent is telling me it will go once the house is aired etc. Has anyone experience of this, is it going to be that easy or will that funky smell linger?
