Jungle pets tank here. Delivery charge is extra I think. They can make one any dimensions you want - eg 40” x 20” deep by 18” tall (that is basically 100cm x 50 Cm). I had a quote for that kind of size once and it was about the same price as the standard four foot one but that is only 15” deep so not really deep enough floorspace wise. Some females are very active and need a lot of space and chew anything. Detolf would be half the price but you may get her chewing the bars.
