Let’s make it simple
A few things you might be wondering.
Still have a question? We’re here to help.
Talk to the OnlyCat teamDoes OnlyCat need a subscription?
The one-time purchase works without a subscription for core features. The subscription version needs an active rolling subscription to operate. Current options and terms are explained on the product page.
Compare the purchase optionsCan I set different rules for each cat?
Yes. Microchip recognition lets you choose entry, exit and curfew rules for individual cats. One cat can stay in while another has access to the garden.
See how curfews workDoes it need Wi-Fi?
Wi-Fi is needed for setup and app features. The one-time version can continue its door functions without internet after setup. The subscription version needs connectivity to check its subscription.
Getting startedWill it work for a bigger cat?
OnlyCat is designed for cats up to 6 kg (13 lb). Customers typically report no issues with cats around 8 kg, but this cannot be guaranteed. Check the opening and talk to us if you are unsure.
Dimensions and specificationsCan I replace my existing cat flap?
OnlyCat is a drop-in swap for many existing cutouts and cat flap brands. The standard rectangular cutout is 165 × 172 mm. Check your existing opening and mounting needs before ordering.

Entry pauses for that attempt. Your cat can return without the prey and be admitted immediately, subject to the entry permissions you have set. The app lets you see the event.
