My younger sister has a beardie and her terrarium is 3 sides laminated wood and 1 side glass panels. I am trying to secure a hammock for the little lady and the suction cups won’t stick to the wood sides. Any suggestions for glues/silicones/etc that will help secure the suction cups? I don’t care if you can’t remove them later on. I just want our little lady to have another safe feature in her home
