So we decided rather than spend a lot of money buying a viv for Petey that looks good in our living room, we'd build one ourselves. It measures L: 53 in. x W: 17 in. x H: 18 in.
Total price wound up being well under $200 and breaks down as follows:
Solid wood shelves from Craigslist: $25
Door (second hand from The Re Store with hinges attached)/ handles/ lock hooks/ vent: $10
Lighting (Hydrofarm FLT514 48 in. T5 fixture, Zilla Desert 50 UVB 48 in., ceramic socket)- $70
Grout/ sealant/ glue/ wood piece for front- $25
We bought the cabinets it rests on for $30 on Craigslist as well, and the heat lamp, desert background, feed dish and slate tile scraps we already had, the styrofoam for her cave for free from a friend that just bought furniture.
We chopped the shelving down the length needed, applied foil to the top to help spread light and warmth (this is an experiment, we don't know if it's actually doing anything haha). In the front we attached a piece of trim with gaps for ventilation, as well as a vent in the back. The door hinges from the top for easy cleanup of the floor. We use hooks to keep it locked either up or down.
She loves it. She's much more active and lively and will watch TV with us from it.
