The best option would be Elmer’s Wood Glue. This is a non-toxic glue, easy to clean up, and cheaper than buying a new tree! Even though it’s not toxic, you shouldn’t let your cat ingest it, since it can cause distress in her GI tract.
Just apply the glue to the cat tree, and then add the sisal rope or carpet. If you’re doing minor repairs, it’s not necessary to use hot glue. Once you’ve applied the glue, you’ll need to press down on the area for a few minutes.
The carpet on cat trees usually get loose, and wood glue would be enough to repair this. But, if you need to replace a bigger area, you can pick up carpet scraps from different places – such as a big store that’s going to throw them anyway.
he sisal rope is pretty easy to get. You can find some on Amazon, and you can also use any kind of similar twine or rope material. Just make sure to use the one that’s safe for pets!
You should avoidglues that contain diphenylmethane diisocyanate. Once it comes in contact with gastric liquids, this glue ingestion will result in a stomach foreign body.
