1. Size

This will depend on the size of your cat. Kittens, for one, may find it difficult to get into a regular sized litter box. A large cat, meanwhile, may find a small box difficult to maneuver around.

The rule of thumb in choosing a cat litter box is that it should be at least 1.5 times the size of your pet.

Small cat boxes are best for small cats and kittens. Medium sized boxes should work well for one box, while a large litter box could house one or two cats. Extra large litter boxes are useful for cat owners with three or more pets.

2. Type

Auto litter boxes can be classified into types. The most basic are the open type which is rectangular shaped. It’s easy to operate, with sensors that can activate the cleaning cycle 10 minutes after your pet leaves the box. It’s cheap, too, so it is a good option for pet owners who don’t want to spend much. But the problem with an open litter box is that it may not suit cats that prefer privacy when they litter.

Then there are the covered auto litter boxes. Cats will get lots of privacy with this type of auto litter box. The cover also controls the odor and makes it less likely for the litter to be spilled over the side when your pet is vigorously digging.

There are also cat litter boxes with optional covers. It can be covered and uncovered. It also does a decent job of controlling the odor because of a rake that transfers solid waste into a receptacle. The latter has to be emptied periodically. Many people think the best automatic cat litter box is of this type. The major downside is that it is pricey.

Last but not the least are the self-washing and self-flushing litter boxes. It is the most expensive of the four types. But it is very convenient and advanced as it completely flushes the waste of your cat. Think of it like your cat’s toilet bowl. It also keeps your house smelling clean.

Aside from the price, another disadvantage is that it will only have to be placed in the laundry room or toilet. It requires a cold water line and waste water drain to work properly.

3. The size of your apartment/house

If you have a mansion, then you don’t have to consider this factor. But if you live in an apartment, studio, or condominium, then you should get an automatic litter box that isn’t bulky and too noisy during cleaning cycles and also use a litter mat to help you ease in cleaning.

An automatic cat litter box with a silent option will not embarrass you and bother your neighbors. You can also get one with a short cleaning cycle. Other units have a sleep mode that delays the cleaning cycle so that you won’t wake up to the irritating sound of the unit in the middle of the night.

4. Age and health condition of your pet.

Older cats no longer have good night vision that they had when they were younger. Thus you may get them a cat litter box with a night light, so she will be able to find it even in the dark.

You can also look for an automatic litter box with a health counter that tracks the cat’s usage of the unit. It can help you in identifying changes in the metabolism of your cat, and perhaps give you something to tell her vet.

5. Your cat’s size

The average domestic cat should not weigh more than 10 pounds. Most automatic litter boxes can accommodate a cat of the standard size. But if your feline friend weighs more than 15 pounds, then you would have to look for heavy duty auto litter boxes.

If you own kitties that weigh less than five pounds or not big and tall enough to be detected by motion sensors, choose an electronic litter box with a manual start option
