Second-hand cat gear: what to buy, what to avoid

🐈 Cats · 🧰 Accessories · updated 2026-07-11

Buying your cat’s equipment second-hand saves 50 to 70% on the starter bill: a cat tree costing 120 € new can be found for 30 or 40 € on second-hand marketplaces. But not everything is worth buying used: some items pose a genuine hygiene or safety problem. Here is the sorting, category by category.

Which second-hand accessories can you buy without hesitation?

Which items are better bought new?

A second-hand litter box is not recommended: scratched plastic retains another cat’s smell despite washing, which can trigger marking or refusal of the box — at 10 to 20 € new, the risk is not worth it. Same caution for fabric toys steeped in odours and scratchers already marked. Plush beds without removable covers are hard to sanitise: walk on by. The full starter kit is detailed in our article on first-kitten equipment mistakes.

The second-hand cat tree: bargain or trouble magnet?

It is the biggest saving available — with conditions. Inspect the stability of the base, the state of the sisal and above all the smell: a tree marked by a urine-spraying cat is beyond saving. Steam cleaner on the plush parts, a brush over the sisal, 48 h of airing, and your cat will make it its own. At 30 € instead of 120 €, that funds the rest of the kit — see our full budget in how much a cat costs in the first year.

How do you disinfect without dangerous products?

Hot soapy water then a thorough rinse for anything plastic or metal; machine wash at 40-60 °C for textiles; steam for non-washable surfaces. Avoid poorly rinsed concentrated bleach and any perfumed disinfectant. If the previous owner mentions a sick cat (ringworm, cat flu), pass: some agents survive for months.

Frequently asked questions

Where can you find second-hand cat gear?

General classified-ad sites, local groups, car-boot sales, and animal welfare charities that resell donated equipment.

Is a second-hand electronic toy reliable?

Test it on the spot, fresh batteries in hand. With no demonstration possible, treat the price as that of a half-dead item.

What should you check on a used water fountain?

The state of the pump (limescale), the absence of cracks, and the availability of replacement filters: a fountain with no compatible filters is worthless.
