Quick answer

Our top pick for most indoor cats is the PetSafe ScoopFree Ultra Self-Cleaning Litter Box. It automatically rakes waste into a covered trap, keeping the box fresh for weeks and reducing daily scooping. For multi-cat households or those on a budget, the Frisco High Sided Cat Litter Box offers a spacious, no-frills design that contains mess and is easy to clean.

What to consider for Cat Litter Box For Indoor Cats

Indoor cats spend most of their time inside, so their litter box must control odour effectively and be placed in a quiet, accessible location. Consider the box size: your cat should be able to turn around comfortably. Covered boxes offer privacy but may trap smells; open boxes are easier to clean but can scatter litter. Self-cleaning options reduce daily maintenance but require compatible litter. Also think about the number of cats: the rule of thumb is one box per cat plus one extra.

What to look for in a cat litter or litter-area product

When choosing a litter box, prioritize strong clumping and odour control to keep your home fresh. Low dust is important for feline respiratory health, especially for cats with asthma or allergies. Look for low-tracking designs, such as high sides or top-entry boxes, to minimize scattered litter. For multi-cat households, a larger box or self-cleaning model helps maintain cleanliness. Unscented options are often best for sensitive cats who may avoid strong fragrances.

How we chose these picks

We evaluated litter boxes based on size, ease of cleaning, odour control, and cat comfort.
We considered customer reviews and ratings from verified purchasers on Amazon.
We prioritized products with durable construction and safety features, such as non-toxic materials.

Never ranked a product higher just because it pays a commission.

What to avoid

Heavily scented litters that can put cats off using the box; many cats prefer unscented.
High-dust clay litters for cats with breathing issues; choose low-dust or natural alternatives.
A box that is too small or too few boxes for the number of cats; this can lead to inappropriate elimination.
Sudden litter changes; always transition gradually over a week by mixing old and new litter.

Why this matters

Indoor cats typically spend more time near their litter box, so odour control and easy maintenance are critical for both cat comfort and household harmony. Choosing a box that matches your cat's preferences can prevent behavioural issues.

The Options

Types Explained

Open Litter Box

A simple, uncovered tray with low or high sides. Easy to clean and allows cats to see their surroundings, which some prefer. However, it offers no odour containment and can scatter litter more.

Best for: Cats that dislike enclosed spaces, and owners who prioritize easy cleaning and monitoring.

Covered or Hooded Litter Box

A box with a removable hood or dome that provides privacy and helps contain odour and litter. Some have a carbon filter or a flap door. The enclosed space can trap smells and may feel confining for larger cats.

Best for: Owners who want to reduce litter scatter and odour, and cats that prefer privacy.

Self-Cleaning Litter Box

An automatic box that rakes, sifts, or cycles waste into a sealed compartment after each use. Reduces daily scooping and keeps litter fresher longer. Requires electricity and compatible litter, and may be noisy or scare timid cats.

Key Buying Factors

Size and Accessibility

The box should be large enough for your cat to turn around and dig comfortably. For kittens or senior cats, a lower entry height is important. Measure your cat and choose a box that is at least 1.5 times their length.

Ease of Cleaning

Look for smooth, non-porous surfaces that resist staining and odour. Self-cleaning boxes reduce daily work but require compatible litter and occasional deep cleaning. Removable liners or trays can simplify maintenance.

Odour Control

Covered boxes and carbon filters help contain smells, but they can trap odour inside if not cleaned regularly. Self-cleaning models remove waste quickly. Some boxes have built-in deodorizers or work best with specific litter types.

Litter Tracking

High-sided boxes, top-entry designs, and litter mats can reduce tracking. Some boxes have special entryways that help clean paws. Consider your flooring and how much mess you can tolerate.

Material and Durability

Most boxes are made of plastic, but quality varies. Thicker, BPA-free plastic resists cracking and staining. Stainless steel boxes are more durable and easier to sanitize but are heavier and more expensive.

Living With It

Care, Cost and Maintenance

Daily Scooping

Scoop solid waste and clumps at least once a day. This prevents odour buildup and keeps the box inviting for your cat. Use a slotted scoop to separate waste from clean litter. Dispose of waste in a sealed bag or designated bin.

Weekly Deep Cleaning

Empty all litter and wash the box with mild soap and warm water weekly. Avoid harsh chemicals like bleach or ammonia, which can deter cats. Rinse thoroughly and dry before adding fresh litter. Replace the box if it becomes scratched or stained.

Litter Replacement Schedule

For clumping litter, completely replace the litter every 2 to 4 weeks, depending on usage and number of cats. Non-clumping litter needs more frequent changes, typically weekly. Always follow the manufacturer's recommendations for your specific litter type.

Pro tip

Place a litter mat both inside and outside the box to catch tracking, and consider using a stainless steel box if you struggle with plastic odour absorption.

Frequently asked questions

How often should I change the litter in the box?

For clumping litter, scoop daily and fully replace the litter every 2 to 4 weeks. For non-clumping litter, replace it entirely at least once a week. If you have multiple cats, you may need to change more frequently. Always monitor odour and your cat's behaviour; if the box smells or your cat avoids it, increase the change frequency.

What is the difference between clumping and non-clumping litter?

Clumping litter forms solid clumps when wet, making it easy to scoop out urine and feces. It typically lasts longer between full changes and offers better odour control. Non-clumping litter absorbs moisture but does not form clumps; it must be replaced more often and can become saturated quickly. Clumping is generally preferred for indoor cats.

Can dust from cat litter affect my cat's breathing?

Yes, high-dust litters can irritate a cat's respiratory system, especially in cats with asthma or allergies. Low-dust or dust-free options, such as those made from paper, wood, or certain clays, are safer. If your cat coughs or sneezes after using the box, consider switching to a low-dust litter and consult your veterinarian.

How can I control litter box odour effectively?

Scoop daily, use a litter with activated charcoal or baking soda, and place the box in a well-ventilated area. Consider a self-cleaning box or a covered box with a carbon filter. Deep clean the box weekly and replace litter regularly. Avoid scented litters, as some cats dislike them. If odour persists, check for health issues with your vet.

How many litter boxes do I need for multiple cats?

The general rule is one litter box per cat plus one extra. For example, two cats need three boxes. Place them in different quiet locations to reduce competition and territorial issues. Each cat should have easy access to a box without feeling trapped. This setup helps prevent inappropriate elimination.

What are the best low-tracking litter box options?

Top-entry boxes and boxes with high sides or a built-in ramp can reduce tracking. Using a litter mat outside the box helps catch stray granules. Some litters are designed to be larger or heavier, such as crystal or pellet litters, which track less than fine clay. Experiment to find what works best for your cat.

Should I use scented or unscented litter?

Most cats prefer unscented litter because their sense of smell is much stronger than ours. Strong fragrances can deter cats from using the box. Unscented litters are generally safer for sensitive cats. If you want odour control, choose a litter with natural odour absorbers like carbon or baking soda rather than added perfumes.

Why is my cat suddenly avoiding the litter box?

Sudden avoidance can be due to a dirty box, a change in litter type, a new box location, or a medical issue such as a urinary tract infection. Stress from new pets or household changes can also cause this. First, ensure the box is clean and accessible. If the behaviour continues, consult your veterinarian to rule out health problems.

How do I introduce a new litter box to my cat?

Place the new box in a quiet, low-traffic area away from food and water. If switching from a different type, keep the old box available initially. Gradually mix old and new litter if changing types. Show your cat the box and let them explore. Reward them with treats or praise when they use it. Be patient; some cats adapt quickly, others may take a week.
