Cat water fountain guide

Cat Water Fountains: Compact 2L, Shared 1 Gallon, or Battery 5L?

Measure the counter or floor space and trace the cord before choosing a fountain. Catit PIXI 43720 is the compact 2 L model at 8 x 8 x 6.7 in. PetSafe PWW00-13705 holds 128 oz in a 14.3 x 14.3 x 9.3 in plug-in unit and has five spout attachments that make five stream patterns, with adjustable flow strength. Catit 43761 holds 5 L in a 10 in wide, 7.5 in high unit; sensor and timed modes can run on its battery, while continuous mode requires a plug. Its battery claim is up to 45 days in timed mode, not every mode.

The verdict changes if the cat can reach a cord, loose filter part, or damaged pump housing. Keep a plain water bowl available while introducing or troubleshooting any powered station. This comparison uses official specifications, not hands-on testing, and it does not use Amazon price, ratings, reviews, stock, seller copy, badges, or images as evidence.

Ask a veterinarian about a new change in drinking, urination, appetite, vomiting, marked lethargy, or illness signs. A fountain changes water presentation; it does not diagnose, prevent, or treat urinary or kidney disease.

Quick answer

Choose the station burden, not the biggest tank

Compact footprint

Use Catit 43720 when 2 L and its 8 x 8 x 6.7 in size fit the placement; its stainless top is dishwasher-safe.

Shared patterns

Use PetSafe PWW00-13705 when 128 oz, five included stream patterns, and adjustable flow strength fit the shared station.

Timed battery placement

Use Catit 43761 when timed/sensor battery operation meets the need; up to 45 days applies to timed mode, and continuous mode needs a plug.

Choice planner

Start with the home constraint

Best current match: Catit PIXI Drinking Fountain, Stainless Steel (43720)

Which condition decides the placement?

A power cord cannot be routed outside chewing reachA smaller cleaning job matters more than reservoir size

Why it wins: The compact 2 L Catit has the smallest documented reservoir and a dishwasher-safe stainless drinking top.

Condition that changes it: Move to the 128 oz PetSafe when several pets need more shared access, or to the 5 L Catit only when wire-free placement is non-negotiable.

This planner compares official specifications, not hands-on performance. Keep a plain water bowl available while a cat learns a new powered station.

Before you choose

What changes the cat water fountain choice

Reserve first

Choose 2 L, 128 oz, or 5 L by refill headroom and shared access, not by assuming a larger reservoir stays cleaner.

Trace the cord

Map the real outlet route. If a cord crosses chewing or walking space, protect it or make wire-free placement a hard requirement.

Count the surfaces

A larger basin, more streams, filters, pumps, and battery parts all add places that need inspection and cleaning.

Keep a backup

Leave a plain bowl available while the cat learns the fountain and whenever the powered station is apart or not working normally.

Stop on damage

Unplug or stop use for cord damage, leaking near power, pump faults, cracked housings, or loose pieces a cat can chew or swallow.

How each option fits

Reviewed cat water fountain notes

Catit

Catit PIXI Drinking Fountain, Stainless Steel (43720)

Why it stays on the list: Compact 2 L corded station
Setup constraint: Reserve an 8 x 8 x 6.7 in dry, level spot (listed unit weight 678 g), route the USB cord away from chewing and walking paths, and keep a plain water bowl available during the change.
Safety limit: Stop using the fountain for cord damage, pump faults, leaks near powered parts, or any loose piece the cat can chew or swallow.

PetSafe

PetSafe Drinkwell Stainless Multi-Pet Fountain (PWW00-13705)

Why it stays on the list: Shared 128 oz, five-pattern option
Setup constraint: Reserve a 14.3 x 14.3 x 9.3 in dry, level space, give every cat an unblocked approach, route the cord away from chewing, and keep a plain water station as backup.
Safety limit: Stop for pump faults, cord damage, leaks near power, or any filter or fountain part that becomes loose or chewable.

Catit

Catit PIXI Stainless Steel UV-C Wire-Free Fountain 5L (43761)

Why it stays on the list: Battery-mode placement option
Setup constraint: Reserve a 10 in wide x 7.5 in high dry, level space. Battery lasts up to 45 days in timed mode; use a plug for continuous mode and keep plain water available during setup or charging.
Safety limit: UV-C is a documented feature, not proof of sterilization or disease prevention. Stop for battery, pump, leak, housing, or loose-part faults.

Choice

Compact 2 L, shared 128 oz, or wire-free 5 L

Choose Catit 43720 when the 8 x 8 x 6.7 in footprint and 2 L capacity fit the space and refill routine. Its stainless top is dishwasher-safe; compare that part-specific instruction with the other models' component care rather than treating it as an exclusive feature.

Choose PetSafe PWW00-13705 when 128 oz, five included stream patterns, adjustable flow strength, and the 14.3 x 14.3 x 9.3 in footprint fit a shared station. Its fountain body is top-rack dishwasher-safe, but the pump is hand-washed.

Choose Catit 43761 when sensor or timed battery operation solves the cord-placement constraint. Catit lists up to 45 days in timed mode; continuous mode requires a plug. Its 5 L reservoir does not remove filter, pump, or component-cleaning work.

First week

Water fountain first-week checks

Set the fountain on a dry, level surface where the cat has a clear approach and can leave without passing another pet.
Protect every operating cord from chewing and traffic. Catit 43761 avoids a cord only in battery-supported modes; continuous mode needs a plug.
Keep a plain water bowl nearby while the fountain is new, charging, being cleaned, or not flowing normally.
Inspect the drinking surface, filter path, pump, housing, and removable pieces before refilling; follow the maker's care instructions for the exact model.
Stop using damaged powered equipment and contact a veterinarian about new drinking, urination, appetite, vomiting, lethargy, or illness changes.

FAQ

Cat water fountain questions

Which cat water fountain should I choose first?

Compare the measured station space and cord route first: Catit 43720 is 8 x 8 x 6.7 in with 2 L capacity; PetSafe PWW00-13705 is 14.3 x 14.3 x 9.3 in with 128 oz and five stream patterns; Catit 43761 is 10 in wide x 7.5 in high with 5 L and up to 45 days in timed battery mode. Continuous mode on 43761 needs a plug.

Does a bigger reservoir mean less cleaning?

No. Capacity changes refill headroom, not the need to clean the drinking surface, filter path, pump, housing, and removable parts according to the maker's instructions.

Can the 5 L Catit run continuously without a cord?

No. Catit lists sensor, timed, and continuous modes, but continuous mode works only while plugged in. Its up-to-45-day battery statement applies to timed mode; follow the separate filter and cleaning instructions too.

Does UV-C make fountain water medically safer?

This guide treats UV-C only as a documented product feature. It does not claim sterilization, disease prevention, treatment, or guaranteed water safety.

When should I stop using a powered fountain?

Stop for damaged cords, pump or battery faults, leaks near powered parts, cracked housing, or loose pieces a cat can chew or swallow. Ask a veterinarian about concerning changes in drinking or health.
