I am currently using a T-10 with my Blood.She is now about 5'.Changing the newspaper daily because the water box overflowed or was knocked over prompted me to search for a larger cage.A T-25 was my choice,but I didn't order because shipping was too high.I looked around for other cages but some didn't have the sliding glass doors like AP.I thought maybe I should look for a caging company closer to The New York Area (my locality) to avoid shipping costs.Just posting this in case anyone can suggest any caging options,whether by a specific company or other-Thank You-Harold
