How Many Litter Boxes You Actually Need
The standard rule from feline behaviourists is one litter box per cat, plus one extra. So one cat needs two boxes, two cats need three, and so on. This sounds excessive but dramatically reduces inappropriate elimination problems, especially in multi-cat households where territorial dynamics can lead to one cat blocking another from using a shared box.
In larger Canadian homes with multiple floors, place at least one box per level. A senior or arthritic cat may not navigate stairs reliably to reach a basement litter box, leading to accidents that aren't behavioural at all but mobility-related. Multiple boxes also let you spot health issues earlier — changes in one cat's elimination are easier to notice when boxes aren't shared.
Choosing Box Size and Style
Most commercial litter boxes are too small. A proper box should be at least 1.5 times the length of your cat from nose to tail base. For most adult cats, that means a box at least 60 cm long. Many cat owners use under-bed storage containers or cement mixing tubs from hardware stores as oversized litter boxes — much cheaper than 'jumbo' commercial options.
Covered boxes feel more private to humans but trap odours, restrict movement for larger cats, and can make some cats feel cornered. Self-cleaning boxes work for some cats but their motors and movements scare others. If you have a multi-cat household, mix box styles so cats can choose their preference. Skip plastic liners — most cats hate the texture and they often catch on claws.
Litter Selection
Most cats prefer unscented, fine-grained clumping clay litter. Heavily scented litters are designed to please humans but often repel cats. If you're switching litters, transition gradually over a week or two by mixing increasing amounts of new litter with the old. Sudden switches commonly cause cats to refuse the box.
Alternatives to clay include wood pellet litters (popular in Canada, often cheaper, lighter to carry), corn-based litters, paper-based litters (good for post-surgery cats with declawed paws — though declawing is now banned or restricted in most Canadian provinces), and silica crystals. Try a 'litter box buffet' — multiple boxes side-by-side with different litters — if your cat is having issues to identify the preferred type.
Box Placement
Place boxes in quiet, low-traffic areas where cats won't be ambushed by other pets, children, or sudden noises (avoid placing near furnaces, washing machines, or noisy appliances). Provide multiple exit routes — a box cornered against three walls feels like a trap to a vulnerable cat.
Don't place food and water near litter boxes. Cats instinctively avoid eliminating near eating areas. In small Canadian apartments where space is tight, this can be challenging — get creative with bathrooms, closet floors with the door propped open, or covered furniture pieces designed to disguise litter boxes. Avoid placing boxes in spots requiring stairs for senior cats or kittens still developing coordination.
Cleaning Routines
Scoop solid waste and clumps at least once daily, preferably twice. Cats are fastidious — many will refuse a soiled box and eliminate elsewhere. Top up litter to maintain at least 5 to 8 cm depth so cats can dig and cover properly. Completely empty, wash, and refill the box every 2 to 4 weeks for clay litter, or as the manufacturer recommends for alternative litters.
Clean the box itself with mild dish soap and warm water. Avoid bleach, ammonia-based cleaners (ammonia smells like urine to cats), or strongly scented products. If your cat suddenly stops using a previously accepted box, schedule a vet visit before assuming it's behavioural — UTIs, kidney issues, and arthritis are common medical causes of litter box avoidance, especially in cats over 7 years old.
