How to Choose a Cat Litter Box: Size, Sides and Design
Choose a cat litter box that lets your cat enter, turn, dig and cover waste without pressing against the walls. Body size comes first, followed by entrance height, side height and privacy preference. For most cats, a spacious box in a quiet, accessible location is more important than decorative features.
Quick decision table
| Cat or household need | Useful box feature | Why it helps |
|---|---|---|
| Large cat | Extra-large floor area | Gives the cat room to turn and position comfortably |
| Enthusiastic digger | High sides | Helps contain kicked litter |
| High-peeing cat | High back and side walls | Helps keep urine inside the box |
| Kitten or senior cat | Accessible entrance | Reduces the step required to enter |
| Privacy-seeking cat | Semi-enclosed design | Adds visual privacy while retaining an open entrance |
| Multi-cat home | Multiple boxes in separate locations | Reduces competition and provides choice |
What size litter box does a cat need?
A useful starting point is a box approximately one-and-a-half times the cat’s body length, excluding the tail. This is a guide rather than a strict rule: observe whether your cat can turn freely and dig without repeatedly stepping outside the box.
Many products are labelled “large” or “XL”, but exterior styling can reduce the usable interior. Compare the internal floor area and entrance dimensions, not only the product name.
Open vs enclosed litter boxes
Open cat litter boxes provide airflow, visibility and easy access for scooping. They can suit cats that dislike confined spaces and allow owners to notice changes in waste more easily. High-sided open boxes add scatter control without a roof.
Enclosed or semi-enclosed boxes offer more visual privacy and may contain some kicked litter. They also need regular cleaning and good ventilation, because odour can build up inside. If a cat hesitates at the entrance, crouches uncomfortably or stops using the box, return to a more open option.
Are high-sided litter boxes better?
High sides are particularly helpful for cats that dig vigorously, scatter kitty litter or urinate near the edge. They do not eliminate tracking from paws, and a very high entrance can be difficult for kittens, older cats or cats with limited mobility. Look for a cat toilet or litter tray that combines tall walls with an accessible entry point.
What is the best litter box for a large cat?
Large cats benefit from generous internal floor space and stable walls. The cat should not need to curl its body tightly or stand with the front half outside the box. MICHU XXL cat litter boxes use an open, high-sided format intended to provide more turning room while helping contain scatter.
How many litter boxes are needed?
A widely used starting point is one box per cat plus one additional box. Put them in separate accessible locations rather than treating several boxes side by side as completely separate resources. Cats may have different preferences for urination, defecation, privacy and escape routes.
Where should a litter box be placed?
Choose a quiet, ventilated location that the cat can reach at all times. Keep it away from food and water, avoid trapping the cat in a dead-end corner, and ensure another pet cannot block the approach. Laundry rooms can work, but sudden appliance noise may deter a nervous cat.
How to reduce litter scatter and tracking
- Use a box with enough floor space so the cat can dig without standing at the edge.
- Choose high sides for vigorous diggers.
- Pair the box with a lower-tracking pellet litter when appropriate.
- Place a litter mat outside the entrance.
- Scoop daily so the cat has clean space and does not dig excessively to find it.
- Trim excessive paw fur only when appropriate and done safely.
How often should a litter box be cleaned?
Remove urine clumps and solid waste at least daily. Top up litter to the recommended depth and complete a full empty-and-clean cycle according to the litter instructions and household usage. Use a pet-appropriate cleaner, rinse thoroughly and dry the box before refilling it.
Deep scratches can retain residue and make hygienic cleaning more difficult. Inspect the box regularly and replace it when damage, cracking or persistent odour cannot be resolved through cleaning.
Frequently asked questions
Do cats prefer open or covered litter boxes?
Preferences vary. Many cats value space, cleanliness and easy access more than a roof. Offer an alternative if the cat avoids a covered box or appears cramped inside it.
Can a litter box be too big?
For most healthy adult cats, extra usable space is helpful. The practical limits are placement, stability and whether the entrance is accessible. Very young or mobility-limited cats may need a lower entry.
Why does my cat kick litter out of the box?
Digging and covering are normal behaviours. Scatter increases when the box is cramped, sides are low, litter is very fine or the cat digs enthusiastically. A larger high-sided box and litter mat can help.
Should litter boxes be placed next to each other?
Two boxes side by side may function like one toilet location from the cat’s perspective. In multi-cat homes, distribute boxes so cats have separate access and escape routes.
What litter depth should I use?
Follow the litter manufacturer’s instructions. MICHU Gen3 is generally used at approximately 5 cm depth; other textures and automatic boxes may require different amounts.
