Whisker Litter-Robot 5 · Whisker Litter-Robot 5 Pro

Weight tracking separates cats in the app, and The Quality Edit saw weigh-ins that did not register.

Drawer emptying drops to about every 10 days with one cat; long-term trend history sits behind a $7.99 monthly membership.

You are trading scooping for supervision: the globe keeps you from touching soiled litter, not from being recorded by two always-on cameras aimed at the box.

Litter lock-in: the sifting mechanism is built for clumping litter, so switching to a preferred crystal or natural formula isn’t possible on this hardware.

AI cat identification and extended video storage sit behind a paid Whisker+ subscription, so the headline AI feature is not fully included at the $899 price.

Kittens under 3 lb

Whisker says kittens must weigh at least 3 lb to use it in automatic mode.

Tight closets or under-counter spots

Whisker's drawings put it at 22.2 in wide, 29.9 in tall and 27.25 in deep, with the drawer pulling out at the front.

Homes with only 5 GHz Wi-Fi

Whisker says it requires a 2.4 GHz network; the app, weight tracking and alerts depend on that connection.

Owners using crystal or plant-based litter

Whisker recommends clumping clay litter and says crystal and plant-based litters can upset the drawer-full sensor or fail to sift.

Owners who want full history without a subscription

The free app shows a 7-day view; up to two years of trends needs Whisker+ at $7.99 a month, per Whisker.

Households running crystal or silica non-clumping litter

The globe's sifting grate is designed around clumping litter; crystal and other non-clumping formulas do not separate correctly and are not manufacturer-supported.

Homes with kittens under the 3 lb sensor minimum

The weight sensor confirms a session has ended starting at a registered 3 lb minimum; kittens below that weight cannot reliably trigger automatic cycling until they grow.

Households not comfortable with an always-on in-home camera

Both the forward-facing and in-globe cameras record and will capture people in the room, not only the cat; recordings can be disabled or deleted, but the hardware ships active.

Buyers expecting AI cat identification included at the base price

Facial-recognition cat identification and expanded video storage are gated behind a paid Whisker+ membership; the $899 unit ships with camera hardware but not the full AI tier active.
