Product Details
The Cat Hole Pet Door replacement grooming brush is intended to restore the Cathole Interior Pet Door unit back to its original quality. After excessive use of the interior pet door brush, hair and oil build up in the bristles, so it is important in terms of hygienics for cat owners to replace the cat door brush every so often to ensure cleanliness. The CatHole cat door is great for hiding your cat's litter box and is a great cat door for doors and walls.
Installation Instructions
Step 1: To remove the brush, locate the two “tabs” on the back of the brush. These hold the brush in place as they rest on the lower screw of either side.
Step 2: Bend the two brush ends toward each other to slide it out of the frame.
Please Note: This method can be used to take the brush out for cleaning after it picks up cat hair.
Step 3: Bend the new brush and insert it into the frame assembly. Make sure that the two tabs on either side are resting on the lower screws for a tight hold.
Please Note: Some owners rub catnip on the brush to encourage their cat to brush themselves.
FAQ
How weatherproof is the Cathole door? The cathole is essentially a cutout in your door or wall that is lined with a frame and removable brush. Because of this, we recommend this be used for interior doors and walls only, such as for giving your cat easy access to a hidden litter box, the laundry room, a cat tree, or other living spaces. |
Does this have easy installation? Once the Cathole is installed, replacing the brush is a simple DIY project that can be done in minutes. |
Can my dog use the Cathole? While some pet owners have been able to find cat doors that small dogs can use (such as some large cat doors from Cat Mate, Ideal Pet Products, Petsafe, and Sureflap Microchip pet doors), small dogs will have difficulty squeezing through the Cathole. It's best if you get them a dog door of their own. |

Works
Works fine to replace my used brush. Wish it wasn't quite so expensive though...
Love it!
My cats love this. I have been using this cat door for a few years before I finally got around to replacing the brush. It still works fine but it has gotten kinda gross from use.
Perfect Replacment
Fit perfectly. Great replacement brush for my Cat Hole door.
Love It
It works really good, but would be cool if they had colors other than white.
Cats love the brush
We have the cathole door and I'm convinced my cats walk through more than they need to just to use the brush. Clean regularly by popping out the brush and pulling off the fur. Getting a replacement for hygienic reasons also because one of the cats has taken a liking to gnawing on the brush.
