Lola is about 3ft long and I had her in something close to the 1986 model.
She is now in a 1995. I dont see the harm in the 1986, we had a large half log and a shoebox type hide in it and she seemed just fine, she spent alot of time climbing on things. In her larger home she spends more time strectching out on the sides and crawling under her astro truf.
