This is a specific conversation about Cat litter boxes — size, type, and placement — ask about yours and get one honest answer for your exact situation.

British Shorthairs are one of the heaviest domestic cat breeds — a fully grown male can hit 8kg or more — and most standard litter boxes are genuinely too small and too flimsy for them. The box tips, the sides are too low, and the cat ends up half-hanging out. Most litter boxes are sized for an average cat, but yours needs something at least 1.5 times their body length and sturdy enough not to flex underfoot. Covered boxes, while tidier for us, often make stocky cats feel cramped and trapped — so I'd usually steer clear of those for a British Shorthair. To make sure I point you to the right thing: is your cat male or female, roughly how heavy are they, and are there any current issues — avoiding the box, spillage, litter scatter?
He's male, about 7.5kg. He's been stepping over the side of his current box and getting litter everywhere, and sometimes he doesn't seem to want to go in at all.

That's a classic sign the box is too small and possibly too shallow — he's having to crouch awkwardly to fit, and for a proud, independent breed like a British Shorthair, discomfort quickly turns into avoidance. You need something with high sides to catch the scatter, a genuinely wide base so he can turn around without stepping out, and enough structural rigidity that it doesn't shift under his weight. What does his current box look like — open top, covered, rough dimensions?
It's a basic open-top plastic tray, probably about 40cm long. No lid.

Right, 40cm is about half of what he needs. For a 7.5kg British Shorthair, you want something closer to 55–60cm in length with high sides — ideally 20cm or more — so the litter stays in and he can dig and turn without feeling penned in. My recommendation is the Savic Senator Open Cat Litter Tray. It's 56cm long, has sides around 22cm high, and is made from thick, rigid polypropylene that doesn't flex under a heavy cat. It's open-topped so he won't feel trapped, the high back catches scatter, and the lower front entry means he can step in without climbing. It's widely available on Amazon UK and holds up well over time — no warping, no cracking. One box won't cut it long-term if you add a second cat, but for a single large male, this is the right size.
That sounds good. Will the high sides actually stop all the litter going everywhere? He's a serious digger.
inparticular.ai
High sides help a lot, but no open box eliminates scatter entirely with a dedicated digger. The Savic Senator's 22cm back and side walls will catch most of it. If he's flicking from the front entry point, putting a small litter-catching mat directly in front of the box picks up whatever escapes on his paws as he steps out. That combination — high-sided box plus a mat — is the practical solution most people land on. Don't bother with a hood to solve the scatter problem; for a British Shorthair it will likely bring back the avoidance issue.
Makes sense. How often should I be cleaning it for a cat his size?
inparticular.ai
Daily scooping is the baseline — bigger cats produce more waste and British Shorthairs in particular are fastidious. If the box gets dirty, they'll find somewhere else to go. A full litter change and wash-out every one to two weeks keeps odour and bacteria in check. With the Savic Senator's depth, you can use a decent litter depth of around 7–8cm, which gives him room to dig properly and helps with odour between cleans.
