My advice is spend the extra for a T10. I have 3 T8s and 3 T10s as well as 3 T25s and i wish i would have just waited for T10s. I have one of my T8s empty and is being used as a housing cage for when i want to clean quick and dont want to have to watch snakes i got out. So i stuff them in the T8 so i can focus on cleaning. But the extra 3 inches doesnt sound like much but it is when you clean the cages lol.
