Cathole Cat Door

This is a cat door for interior door use only. A typical example is to allow a cat access to a litter box kept inside a closet. The cat hole for interior wood door installation can be installed in solid or hollow-core doors, and is a very versitile inside cat door. The brush (shown) serves to groom the cat as he passes through.

These wood arches come unfinished and in one size only. The interior cat doors shown have been stained to match the door.

  • Like it review by Bill
    5 5 Like it

    Really liked how you can finish it however you need, makes it so it almost totally invisible so its not an eyesore like other doors. Also it is just the right size for the cat and keeps the dogs out of the cat liter. Good non-expensive solution.

    5 5 Good product

    Easy, to install, easy to train, easy to use. Highly recommend for indoor use and for cats who do not like swinging flaps.

  • Cat loves it! review by Rose
    5 5 Cat loves it!

    Super easy to install in my door and looks great - it was also easy to paint to match the color of our interior trim. The brush is a great bonus.....actually I think my cat likes the brush more than she likes the door. Great buy!

  • My kitten loves the door! review by Ali Cat
    5 4 My kitten loves the door!

    This is the perfect cat door for me. I have two dogs who love to eat the cat food (and other things cat related that I won't mention). Using this door allows my kitty privacy and keeps my doggies at bay.

    The instructions are vey simple. My son cut out the hole for me in just a few minutes and the installation took less than 15 minutes.

    My only negative is that the materials used didn't really reflect the price point. I've had it 3 months and it is working perfectly.

  • Great product! review by Crazy cat lady
    5 5 Great product!

    We bought one several years ago for our 3 cats so they could get to the basement without the dog following them - and they love it! Easy to install and the brush is an added benefit. Recently bought a 2nd one for my daughter so her cat can escape the dog without having to leave the basement door open.

  • Works Great review by JB
    5 5 Works Great

    We installed the cat door about 3 months ago and it works perfectly. Cats picked it up without delay and it looks great

  • love it review by kat
    5 5 love it

    It's very cute and looks nicer than the regular cat doors. The only thing is if you have the hollow doors then you can't attach the brush trim too easily. (my carpenter inserted two pieces of wood on either side on the inside of the door and I used double sided tape) Also it keeps my dog out of that room where as the regular cat door which is supposed to be for cats 15lbs still allows my 20lb dog to get thru which defeats the whole purpose. Now I wish I had used the cat holes in my other two doors.

  • Great idea review by KC's Mom

    Works great -- looks great -- great conversation starter when visitors first see it too.

  • Love it! review by Arlene

    I bought this cat door and had it put on the basement door. Now I can close the door and keep the dogs out of the cat litter. The cat seems to love it - she secretly watches from the basement side.
    Everyone who visits thinks it's the cutest door!

  • Works great! review by My sister

    I bought this for my sister who has two cats and two dogs. The one cat is terrified of the dogs. Both of the cats love this door. My sister can keep the cat food and the litter separate from the dogs, and the terrified cat is getting more confident as she waits for the dog's snout to appear in front of the Cathole so she can swat at it. In addition, it gives the two cats the freedom to leave the room at will knowing they can return safely through the cat door if they get chased by the dogs. This was a great buy!

  • Great- works perfectly review by New cat owner

    This door works exactly as advertised. It keeps my dog out - she likes the taste of cat poop. I did have to take the brush out as my cat has gotten too fat.

  • Perfect door! review by Lynn

    Was looking for a way to isolate my litter box while ensuring my dogs could not get to the box. My husband installed the Pet Door on an out of the way closet in 30 minutes due to the easy to follow instructions. Now my cats have an secluded to use without being disturbed by the dogs. I do recommend this Pet Door to anyone wanting to provide their cat a cozy location that is not very noticeable to my visitors. Oh, everyone that sees it thinks it is so cute!!

    5 5 Great Cat Door

    Bought for our cat and she took to it great and the size was not an issue. Now my daughter is moving out and asked me to order one for her new house. Great Idea - great door!

  • really need a larger version also review by KS
    5 4 really need a larger version also

    I totally agree with the previous reviewers. This is the best looking indoor cat door I have found but it is too small . I really don't understand why you haven't created small , medium and large as other cat door options have.I fear you are losing a lot of business because of it.K

  • Offer another size? review by mere de deux
    5 4 Offer another size?

    Love the idea of this, but we have a larger breed cat and she wouldn't be able to fit in the opening. Perhaps it would be a good idea to ffer a larger size option.

  • Too small review by Kitty Lover
    5 4 Too small

    I love this idea, but agree with another reviewer that it is too small. I think about 6" wide by 12" tall. I have two BIG cats.

    I have bought two of these for different homes over the years and it has worked great. I just bought a condo and was considering another one and that is why I am here again.

  • cathole-inside pet door needs to be larger review by jane
    5 3 cathole-inside pet door needs to be larger

    great product but too short and too narrow for my cat.
    Offering a larger size would likely create more interest in this product.
