Cerebellar Hypoplasia (CH): The "Wobbly Cat" Setup

For cats with Cerebellar Hypoplasia (CH), which causes wobbly movement and balance issues, use a low-entry litter box. The sides should be no higher than 6 inches and internal dimensions at least 21.6 x 16.5 x 13 inches (or 1.5x the cat's nose-to-tail length) to allow easy access, turning, and digging without falling. A 6-inch side height helps prevent litter kick-out while enabling safe entry for wobbly CH cats.

For wobbly cats with cerebellar hypoplasia (CH), it is best to use a high-sided litter box with low entry (e.g., a commercial high-sided model or a custom large plastic storage bin with a cut-out side hole) to provide walls for leaning against. Avoid standard toilets or seats due to balance risks, although specialized products offering a stable, non-slip clip-on seat can be an advanced training option for some cats. High-sided walls, typically 10-12 inches tall, enhance stability.

For CH (cerebellar hypoplasia) or “wobbly” cats, practical high-sided litter boxes commonly use wall heights of about 6–8 inches (15–20 cm), paired with a lower entry cutout around 3–5 inches (7.5–12.5 cm). This design maintains accessibility while containing scatter and high-aim urine. High sides are particularly recommended for large or messy cats, with commercial designs and shields often adding box wall height from 6 inches up to roughly 14 inches total. A 6-inch side height is a functional baseline for “high sides” in many stainless-steel and XL litter boxes marketed for big, messy cats.

Scoop solid waste from the litter box at least once daily using a fine-mesh litter scoop. Perform weekly deep cleaning by emptying, rinsing with hot water and mild dish soap, drying, and then refilling with 2-3 inches of fresh clumping litter. Conduct monthly sanitization by soaking the box in a diluted bleach solution (1 tablespoon per gallon of water) for exactly 5 minutes, followed by thorough rinsing and air drying.

Stainless steel enclosed litter box models, such as those from Furr Bby, can often be easily modified. Some designs feature a dual-layer lid that allows conversion between fully enclosed, semi-enclosed, and open configurations without tools, often using push-button mechanisms. Overlapping edges and snap connections are commonly integrated to prevent leaks. Standard dimensions for many such models are around 23.9"L x 15.9"W x 15.4"H, typically holding about 8 gallons of litter.

For many CH cats, a low-sided litter box with a 2–3 inch (5–7.5 cm) high entry is recommended. The box should be at least 13–24 inches (33–61 cm) long and have 3–6 inches (7.5–15 cm) of surrounding clearance. Place it on a non-slip surface to reduce falls, mis-steps, and accidents. Covered or standard high-sided boxes are usually discouraged unless the entry lip is similarly low, as balance and coordination are impaired. An entry height of approximately 2–3 inches (5–7.5 cm) is ideal for a wobbly CH cat litter box.
