Should be fine as long as you let them dry for several days. You dont want even a hint of the odor from the uncured paint before putting it in contact with your cham. I spray paint the the wooden cages I build and have not had any issues. I usually plan on at least a week of drying time before putting a cham in.
oh god i dont want benny doing that. he might use bad profanity cuz he is always hissing when i go in the basement to care for him. couldnt he also use polyuthaine? i was told it makes mold and stuff less likely to grow.
