Automatic Litter Box XXL: Is It Worth It and Who Needs It?
Founder Prime AnimalZ · 16 February 2026 · 5 min read
Short answer
An automatic litter tray XXL is worth it for cats of 6 kg+, for households with 2 or more cats, and for owners who want to empty the box less frequently. For an average cat of 4 kg, a standard size is sufficient.
- ✓ XXL needed: cat over 6 kg, Maine Coon, 2 or more cats
- ✓ XXL advantage: larger waste drawer = less frequent emptying
- ✓ XXL disadvantage: more floor space needed, higher purchase price
The biggest mistake when buying a litter tray is choosing one that is too small. A cat needs to be able to turn around comfortably inside. For large breeds or multiple cats, a standard self-cleaning litter tray quickly becomes too small, leading to the cat refusing the box or going outside it.
When do you need an XXL?
| Situation | Advice | Reason |
|---|---|---|
| 1 cat, under 5 kg | Standard | Comfortable space, smaller footprint at home |
| 1 cat, 5 to 7 kg | Standard or XXL | Borderline: choose XXL if the cat is large-framed |
| 1 cat, over 7 kg (Maine Coon, Ragdoll) | ✓ XXL | Body length requires more turning room |
| 2 cats | ✓ XXL recommended | Larger waste drawer = less emptying, less territorial conflict |
| 3 or more cats | ✓ 2 boxes | 1 box per cat plus 1 extra is the standard rule |
| Often away from home (work, travel) | ✓ XXL | Larger waste drawer lasts longer without emptying |
Standard vs XXL: comparison

Frequently asked questions
How big should a litter tray be for a Maine Coon?
A Maine Coon is on average 50 to 70 cm long. The litter tray should be at least 1.5 times the body length, so a minimum of 75 cm. A standard self-cleaning litter tray of 45 cm diameter is too small. An XXL model is not a luxury for these breeds but a necessity.
Can I use an XXL box for 2 cats?
An XXL is better than two standard boxes for 2 cats in terms of space, but the traditional recommendation remains: 1 box per cat plus 1 extra. With 2 cats: start with 1 XXL and add a second if you notice territorial conflict.
How often do I need to empty the waste drawer of an XXL?
With 1 cat: on average once a week. With 2 cats: twice a week. The XXL waste drawer is larger than the standard, so it fills up more slowly.
