Why I Chose the Halo XL Litter Box for Panther: A Veterinarian’s Perspective
If you’ve followed my adventures in veterinary medicine and cat life for any length of time, you probably know Panther.
Panther was once our hospital cat. He has since “mostly” retired from his hospital duties and moved into a home of his own—a custom-built 8′ x 12′ cat house that is every bit as special as he is.
Don’t worry! His house is surrounded by a large Purrfect Fence to provide him a safe outdoor space to chill!
And because Panther is an all-black cat, I couldn’t resist giving his new space one more black-and-black upgrade: the Halo XL litter box in Onyx Black from Huckwell.
It looks fantastic in the corner of his little house. But as a veterinarian, the aesthetics aren’t actually what convinced me to choose it.
The design did.
Oh, PS, I get nothing for recommending the Halo box. I support the product and the brand. That’s it.

Litter boxes are a bigger part of feline health than many people realize
When we talk about cat health, we tend to focus on food, vaccinations, parasite prevention, dental care and annual examinations.
But I spend a lot of time talking to cat owners about something much less glamorous:
The litter box.
A cat’s litter box is an important part of their daily environment, and problems with the box can contribute to house soiling (don’t call it inappropriate elimination!), litter-box avoidance and stress. A cat who suddenly stops using the litter box should also never simply be labeled “bad” or “spiteful.” Medical problems—including urinary disease, gastrointestinal disease, arthritis and other painful conditions—can change litter-box behavior.
From a veterinary perspective, I want a litter box to accomplish several things:
- Give the cat enough room to comfortably turn around and position themselves.
- Allow normal digging and covering behavior.
- Be easy to keep genuinely clean.
- Avoid surfaces that retain odors and residue.
- Be accessible and comfortable for the individual cat.
- Be placed somewhere the cat feels safe.
The Halo checks several of those boxes—literally.

Size matters more than most people think (Oh, and they offer an Extra Tall version now).
One of my biggest complaints about conventional litter boxes is that many are simply too small.
The general veterinary recommendation is that a litter box should provide enough space for a cat to turn around comfortably, with many feline guidelines using approximately 1.5 times the cat’s body length as a useful sizing target.
That becomes particularly important with large cats.
The Halo XL has an interior diameter of approximately 23 inches, giving a cat considerably more room than the typical small, rectangular litter pan. Huckwell specifically designed the XL for larger cats and multi-cat households.
And even if your cat isn’t a Maine Coon or another large breed, I think there is something to be said for giving cats more usable space when you have the room for it.
Cats don’t necessarily want to walk into a box, immediately squat and walk back out.
They may circle.
They may dig.
They may change position.
They may turn around to cover their waste.
A spacious box allows those behaviors to happen naturally.

Why stainless steel caught my veterinary attention
The other major feature of the Halo is its construction.
It is made from 304 stainless steel, rather than plastic. That matters because litter boxes are exposed to urine, feces, moisture, litter dust and plenty of vigorous digging every single day.
Plastic can become scratched over time. Those scratches can make a plastic litter box more difficult to thoroughly clean and can contribute to persistent odors and staining.
Stainless steel is non-porous and can be cleaned much more thoroughly. Huckwell describes the 304 stainless-steel surface as resistant to odor, staining and moisture and designed for repeated cleaning.
As a veterinarian, cleanability is a feature I care about.
And as someone who has cleaned a lot of litter boxes, I appreciate it from a very practical perspective, too.

The round design is surprisingly functional
At first glance, the Halo’s round shape may seem like a style choice.
I don’t think it is just that.
A traditional rectangular litter box has four corners. Those corners can become collection points for litter, urine and fecal material, particularly when a cat digs or kicks litter around.
The Halo’s circular interior gives the cat an open area without those corners interrupting their movement. Huckwell describes the design as providing unrestricted turning space and easier cleaning.
For Panther, it also happens to fit beautifully into the corner of his 8′ x 12′ home.
So I’ll happily admit that the fact that it looks good doesn’t hurt!
And yes, I chose Onyx Black for Panther
This may be the least scientific part of my decision.
Panther is black.
The Halo XL is available in an Onyx Black finish.
Obviously, your cat doesn’t care whether their litter box coordinates with their coat.
But I do.
And there’s something particularly satisfying about putting a sleek black litter box inside Panther’s little black-cat palace.
Huckwell says the Onyx edition was inspired by black cats, who can face challenges with adoption compared with cats of other coat colors.
For Panther, it feels like a perfect match. BECAUSE HE’S BEAUTIFUL AND AMAZING AND I LOVE HIM SO MUCH!

A beautiful litter box can actually be a practical advantage
There is another feature of the Halo that I appreciate as both a veterinarian and a cat owner:
It doesn’t look like something you have to hide.
Litter boxes often get relegated to garages, laundry rooms, bathrooms or other places that may not actually be ideal from the cat’s perspective.
But location matters.
Cats generally benefit from having litter boxes in quiet, accessible areas where they don’t feel trapped or threatened. And in multi-cat homes, litter-box placement becomes even more important because cats may compete over access.
A litter box that is attractive enough to live in the home makes it easier to put the box where it works for the cat—not simply where humans don’t have to look at it.

One important reminder: a great litter box isn’t a substitute for good litter-box management
Even my favorite litter box won’t solve every litter-box problem.
I still recommend scooping regularly, keeping the box in an appropriate location and providing enough boxes for the number of cats in the household.
The familiar veterinary recommendation is one litter box per cat, plus one additional box. So, for example, a two-cat household would ideally have three boxes.
And if your cat suddenly starts urinating outside the box, don’t assume they need a new litter box.
They may need a veterinarian.
Changes in elimination habits can be an important clue that something medical or behavioral is going on.
So, would I recommend the Halo?
As a veterinarian, I like the Halo because several of its design features line up with what I want to see in a good feline litter box:
Adequate space.
A cat-friendly open interior.
A surface that can be thoroughly cleaned.
Durable construction.
And a design that makes it easier—not harder—to keep the box in an appropriate location.
The Halo XL is particularly appealing for large cats or households where a larger litter box makes sense. Its approximately 23-inch interior provides substantially more room than many standard boxes.
For Panther, it checked all the boxes.
It fits perfectly in his new home, it’s easy to clean, and the Onyx Black finish looks like it was made for him.
Most importantly, though, it’s a litter box that gives him plenty of room to behave like a cat.
And that’s really what I want from any product I put into a cat’s environment.
If it makes life better for the cat, easier for the human, and supports good feline health and behavior, I’m interested.
Panther seems pretty happy with his choice, too.
Although, being a cat, he has not provided an official product review.
He’s just sitting next to it looking handsome.
