I have cats occupying my boiler room. Unfortunately, my cats are climbing all over the place and are often tearing the flexible air ducts which provide the house with fresh air and warmth. Image for reference:
After a while, the holes in the ducts get large enough for them to fit through and the curious critters start exploring the newly found hiding places. I want to keep them from harm's way and I'm also sick and tired of repairing the damage.
Here are a couple of things I have considered/tried:
- Replacing the flexible ducts with metal ones - not possible, the ducts are running through some tight spaces and bend very often, and I'm on a limited budget
- Buying a more sturdy duct - the image above shows one which is covered by rubber. This helped to some degree, but the cats are persistent and get through eventually
- Wrapping the ducts in a hard and slippery plastic foil. Somewhat effective, but also not perfect
How can I prevent the cats from tearing the ducts up?
