Mine held for awhile, then a very active girl does a bolt up the ramp and it will run down a bit.They are 12 and 13 months. And thanks I was having trouble with Izzy's color its so lovely Thanks Its so fun to watch their antics especially with so many things they have never had before.
And I know I am planning on fleece soon. But still SO much easier to clean than my old. Good news is Both groups are now using litter pans So less cleaning for me anyway
As for Hammocks I make them at home and the new Midwest ramp covers have velcro on top and my dont slip at all that I have seen
