(Cutting instructions come with each order.WARNING: BIO-THANE NOT RECOMMEND FOR COLD WEATHER USE:
We have heard from a few customers over the past year that their Bio Thane anklets have become stiffer during the colder weather and that this could cause damage to their birds legs. So we recommend to anyone that is using Biothane on their birds in a state that has colder weather to keep a close watch on their birds anklets and legs during the colder weather. You may even want to lift the anklets up on your birds legs to make sure the legs look fine from time to time. Especially if your bird tends to bate off its perch a lot.
