Best Dog Proof Litter Box Buying Guide

Things to Consider When Buying Dog Proof Litter Boxes

There are several types of dog proof litter boxes available so it is worth thinking about the features that you would like to see. Here are a few that you should bear in mind.

  • Size

Don’t forget that your cat has to fit inside this dog proof litter box! If you have a big moggy, you will need a box large enough to accommodate them in comfort. If more than one cat is going to be using the cat’s litter box at the same time, you need a very big box!

  • Entry point

The whole point is that your cat can get in but your dog cannot. A dog proof litter box will have an entrance at the top or at the side. More agile cats will be able to leap in the top but if you have an older cat, a side entrance may be preferable.

  • Litter control

Cats litter can make a terrible mess around your home. It gets caught in your cat’s paws as they are taking a pee or poop and then gets tracked out of the box. Many boxes have grooves or a grid that your cat has to walk over as they leave the box. This removes the litter and keeps your house tidy.

  • Odor control

Some cat litter boxes that are covered can become very smelly because the odors can’t escape. You may want to purchase one that has some form of carbon filter.

Benefits of Dog Proof Cat Litter Box

Dog proof litter boxes are a must for households that have both cats and dogs and where the dogs are showing an unhealthy interest in the litter tray! Some dogs simply ignore the place where the cats go to poop and pee but others are fascinated by them, and this is when the problems begin!

If your dog spends too much time hanging around the litter tray, it can put your cat off using it and they will do their business in another part of the house. Dog proof litter boxes give your kitty some peace and quiet and some privacy.

A dog-proof box also stops your pooch from being able to eat the contents of the litter tray. A dog can pick up a lot of pathogens from eating cat poop and they can become very unwell. The litter itself is also not good for your dog. It could trigger an allergic reaction or it could cause an intestinal blockage.

In addition to the health concerns, a dog in a litter box can be a very messy incident! If you want to avoid the litter being spread all over your house by a naughty pooch, you need one of these!

How to Keep Dog Out of Litter Box

Your dogs’ obsession with the cat litter box can become a real pain for you! As well as purchasing a litter box that will keep a dog out, here are some of the other things that you can do.

  • Place a physical barrier around the litter box

You can physically stop your dog from getting at the litter box using physical barriers. Think about using things such as a baby gate or pet pen. You could also place the litter box in a room that your cat can access but your dog can’t. Latches that only let a door open wide enough to let a cat in are a good idea. You could also install a cat flap on an internal door.

  • Make the litter box less tempting

As disgusting as this may seem, the thing that attracts most dogs to a cat litter box is the poop! So, if you can ensure that you keep the litter box very clean, your dog will not find it as attractive! You can do this by making sure that you move the poop from the box as soon as your cat has finished. Thorough cleaning once a week will also help a lot. An alternative is to invest in an automatic litter box that uses rakes to scrape the poop into a tray. You then remove the tray as necessary.

You can put your dog off the idea of eating cat poop by using a deterrent spray. Apply it to the cat poop and your dog will soon go off the idea!

  • Train your dog to avoid the litter tray

You should be able to control the behavior of your dog and that includes leaving the litter box alone! When your dog approaches the litter box, use the ‘leave’ command and give them a little treat. Repeat this consistently and eventually, the litter box will be safe!
