Why Cats Hesitate at First
Cats are creatures of habit, and a self-cleaning litter box changes three things at once: a new sound (the cleaning cycle), a new smell (fresh plastic and internal mechanisms), and a different shape and footprint than what they're used to.
None of this means your cat dislikes the unit — it usually just means they need a bit of time to decide it's safe.
Before You Start
- Don't remove the old tray straight away. Keep it in place during the transition — having an alternative reduces the pressure on your cat to accept the new unit immediately.
- Place the new unit nearby, not in the exact same high-traffic spot as the old tray at first. This avoids the two competing for the same space while your cat is still deciding.
- Use the same litter your cat is already used to for the first one to two weeks. Switching litter type and switching the box at the same time makes it harder to tell which change is causing hesitation. Browse our litter range if you do plan to switch litter type eventually — just do it after the box transition is settled.
The Step-by-Step Transition
Days 1–2: Let them explore, powered off
Set the unit up but leave it switched off. Let your cat sniff around it, walk past it, and get used to its presence with no noise or movement involved. A few treats or calm praise near the unit can help build a positive association early.
Days 3–4: Introduce the cycle from a distance
Run one manual cleaning cycle while your cat is in another room, so the first time the sound happens, they're not standing right next to it. Afterwards, let them approach and investigate once the cycle has finished and the unit is quiet again.
Days 5–7: Start using it as the primary tray
Begin using the new unit as the main litter box, but keep the old tray nearby as a backup. Most cats will start using the new unit on their own once they've decided it's safe.
Week 2: Phase out the old tray
Gradually move the old tray further away over a few days, then remove it once your cat is reliably using the new unit. If they're still going back to the old spot occasionally, that's normal — give it a little longer before removing it completely.
If Your Cat Won't Go Near It
- Check the placement. A unit tucked into a noisy, high-traffic, or poorly ventilated spot can put cats off regardless of the box itself. See our guide on placement for multi-cat homes — the same principles apply even with a single cat.
- Check the interior space. Larger cats need more room to turn around comfortably, and a tight interior can reduce acceptance. Read automatic litter boxes for large cats: what really matters.
- Add a familiar scent. Moving a small amount of used litter from the old tray into the new unit can help your cat recognise it as their own.
- Slow the cycle timing down if your model allows it. A shorter delay before cleaning can feel startling to a cat who's still nearby.
Normal Hesitation vs Real Stress
It's normal for a cat to sniff, circle, or briefly retreat before committing to a new litter box — and it's fine if they use the old tray alongside the new one for a while.
It's worth paying closer attention if your cat avoids litter entirely for more than 48 hours, starts toileting outside the tray, or shows signs of straining. Straining in particular can indicate a urinary issue unrelated to the box itself, and is worth a vet check rather than assuming it's just hesitation.
FAQs
How long does it take for a cat to get used to an automatic litter box?
Most cats adjust within one to two weeks with a gradual transition. Some take to it within days; others need closer to a month, especially older or more cautious cats.
Should I remove the old litter box right away?
No — keep it in place during the transition period and phase it out gradually once your cat is reliably using the new unit.
What if my cat avoids the litter box completely?
Check placement, interior space, and cycle timing first. If avoidance continues alongside straining or toileting outside the tray, it's worth getting your cat checked by a vet to rule out a urinary issue.
Can kittens use an automatic litter box?
Many households wait until a kitten is a bit older and steadier before introducing an automatic unit, simply because the cycle and movement can be more startling for very young kittens.
Does the type of litter affect acceptance?
Yes. Switching litter type and litter box at the same time makes it harder for your cat to adjust to either. Keep the litter consistent during the transition, then change it later if needed.
