If you have enclosed your yard to make it cat-proof, but there are trees too close to the fence allowing cats a possible escape route, these tree guards are the solution. They are un-obstrusive and discreet, and allow you to keep the trees in your yard. The tree guards are built in such a way that they can be adjusted - to accommodate the tree's growth. There are no bolts or nails going into the tree and harming it. And your cats will always be safe - they will never be able to climb up the tree and go over your fence.

Cost:

Approximately $45 / tree guard (depending on dimensions) + shipping.
