What animals is the OcuTrap R1 designed for?

The OcuTrap R1 is built for medium-sized nuisance wildlife — animals roughly 5–25 lbs that fit comfortably inside the cage. This page covers which species the trap is designed around, which ones are a poor match, and how to set your expectations honestly before you deploy.

Primary target species

The R1 was designed around three groups of animals:

Raccoons — the most common target. Adult raccoons fit the cage well and trigger the sensor reliably.
Feral and stray cats — a natural fit for the cage size, and a frequent use case for TNR (trap-neuter-return) programs and property managers.
Skunks — sized well for the cage. The remote door control is especially useful here: you can manage the trap from the app without startling the animal up close.

Opossums and similarly sized animals in the same weight range also work well, even though they aren't the primary design targets.

They're active at night — plan for it

Raccoons, cats, and skunks are nocturnal or crepuscular: most of their activity happens between dusk and dawn. That matters for how you run the trap:

Bait and arm the trap before dusk, so it's ready when your target starts moving.
Expect alerts overnight. Captures most often happen in the hours after sunset and before sunrise — make sure your notification settings will actually reach you.
Plan a morning check. A captured animal shouldn't sit in the trap through a hot or cold day — see Handling & Releasing a Captured Animal.
Not sure what's visiting? Run Scouting Mode for a night or two first. It photographs whatever shows up without closing the door, so you know what you're targeting before you arm.

Will it fit? Cage size and geometry

The cage interior is 10" wide × 12" high × 32" long (see Technical Specifications for full dimensions).

Fit	Animals	Notes
Comfortable fit	Raccoons, feral/stray cats, skunks, opossums (~5–25 lbs)	Enough room to fully enter and reach bait placed behind the sensor
Tight / poor fit	Large dogs, coyotes, adult beavers, anything much over ~25 lbs	Too large to fully enter — the door can't close safely behind them
Poor match (too small)	Mice, chipmunks, small squirrels, other very small rodents	Fit through the cage easily but are not detected reliably — see below

A good rule of thumb: the animal should be able to walk fully inside the cage with room to spare and reach bait placed near the back. If it has to squeeze in, or the door would close on its body, the R1 is the wrong size for that animal.

What the R1 is not designed for

We'd rather be honest here than have you waste nights on the wrong tool:

Very small rodents (mice, chipmunks, small squirrels). The R1's sensor is tuned for medium-sized animals. Very small animals produce a weak detection signal and may walk through the trap without ever triggering it — especially at larger capture distances, where detection of small animals is less reliable. The R1 is not a rodent trap, and we don't recommend buying it for mice or rats.
Animals larger than the cage. If the animal can't fully enter, the trap can't capture it safely.
Birds and reptiles. Detection is not designed or validated for them.

Targeting something on the small end of the range? Don't take our word for it — or the trap's. Validate with Scouting Mode first: if your target animal shows up in scouting photos and registers a Scout Trigger at your chosen capture distance, you know the trap can actually detect it. If it only appears in photos but never triggers, it's too small for reliable capture at that distance — try a shorter capture distance, or reconsider whether the R1 is the right tool.

Setting up for your target

Once you know your target species:

Follow Deploying Your Trap in the Field for placement, capture distance, and the pre-deployment test.
Set your capture distance for the animal's size — the default 8 in works for most raccoon/cat/skunk setups; see Distance Limits, Sensor Alerts & Errors.
Use bait suited to your target and place it behind the sensor, near the back of the cage.
