PETKIT Bundles Explained: How to Choose the Right Bundle for Your Cat

Quick answer

Choose the EverSweet Max 2 (UVC) Ultimate Bundle if your main goal is cleaner, fresher drinking water and you want spare filters included. Choose the YumShare Solo 2 + EverSweet Ultra if you need scheduled meals and fresh water managed together. If you already own a PETKIT litter box, add the Crystal Litter Set or Purifying Liquid Refill separately rather than buying a bundle built around a fountain or feeder.

A PETKIT bundle is not automatically the right purchase just because it costs less than buying parts separately. Bundles group products around a routine: hydration, feeding, or litter care. The useful question is which routine you are actually trying to fix.

This guide compares the current PETKIT bundles by what they include and who they fit. It also covers the accessory refills that are easy to forget, so you can decide whether a bundle solves your problem or whether a single product plus a refill is the smarter buy.

What a PETKIT bundle actually solves

Bundles exist to remove one decision: which parts go together. The EverSweet Max 2 (UVC) Ultimate Bundle pairs a cordless UVC fountain with a 5-pack of filters, so you are not separately hunting for the right replacement filter later. The YumShare Solo 2 + EverSweet Ultra pairs a feeder with a fountain, covering both scheduled meals and flowing water in one purchase.

That convenience matters most when you are setting up a routine from scratch or replacing several items at once. It matters less if you already own a working fountain or feeder and only need one component. In that case, a bundle can leave you paying for a duplicate device you will never unbox.

• Buy a bundle when you need two or more devices that work as one routine.
• Skip the bundle when you only need a replacement part, filter, or refill.

Decision rule 1: start with the problem, not the discount

Write down the single most annoying part of your current routine. If it is refilling and cleaning a water bowl, a fountain bundle is the match. If it is remembering to feed on time, a feeder-inclusive bundle is the match. If it is litter odor or scooping, neither fountain bundle helps, and you should look at litter box accessories instead.

This ordering prevents the most common bundle mistake: buying the largest discounted set and then discovering the core device does not address your actual pain point. A bundle only saves money if you use every item in it.

• Hydration problem: prioritize a fountain bundle with filters included.
• Feeding schedule problem: prioritize a bundle that includes a feeder.
• Litter problem: buy litter accessories, not a fountain bundle.

Decision rule 2: count the cats and the water volume

More cats drink more water, which means more refills and more frequent filter changes. A bundle that includes a multi-pack of filters is more valuable in a multi-cat home because you will go through them faster. In a single-cat home, the same filter pack may last long enough that the bundle's value is mostly in the fountain itself.

If you are unsure, estimate how often you currently refill water bowls. Frequent refills point toward a larger-capacity fountain setup and a bundle with spare filters. Occasional refills point toward a simpler single-device purchase.

• Two or more cats: filter-inclusive bundles earn their keep faster.
• One cat with low water intake: a single fountain plus one filter pack may be enough.

Decision rule 3: decide whether you want one app or two

The YumShare Solo 2 + EverSweet Ultra bundle combines feeding and hydration, which means one routine to manage rather than two separate devices with separate habits. That is a real benefit for households that travel or work long hours, because both meals and water are handled while you are away.

The trade-off is cost and complexity. If you already own a feeder you trust, adding a second connected device may be unnecessary. Buy the fountain alone and keep your existing feeder.

• Choose the combined bundle if you want feeding and hydration handled together.
• Choose a fountain-only bundle if your feeder already works well.

Accessories that bundles usually leave out

Bundles rarely include cleaning tools or litter consumables. The PETKIT Cleaning Set is a small add-on with a brush and sponge designed for fountain cleaning, and it fits any cleaning case rather than one specific model. If you are buying a fountain bundle, this is the accessory most likely to keep the fountain running smoothly.

For litter box owners, the Crystal Litter Set and Purifying Liquid Refill are separate purchases. The Crystal Litter Set is designed specifically for the Purobot Crystal Duo, and the Purifying Liquid Refill works with litter boxes that have air purifier modules, including Pura X, PuraMax, and PuraMax 2. Check your model before adding either.

• Add a cleaning set when you buy any fountain bundle.
• Confirm your litter box model before buying litter or purifying refills.

Bundle decision rules

• If your main problem is dirty or stale water: Choose the EverSweet Max 2 (UVC) Ultimate Bundle. It includes the fountain and a 5-pack of filters, so you can replace filters without a separate order. Best fit for single-cat and multi-cat homes focused on hydration.
• If your main problem is remembering meals and refills: Choose the YumShare Solo 2 + EverSweet Ultra. It combines scheduled feeding with a fresh water fountain in one setup. Best fit for busy households or owners who travel.
• If you already own a working feeder or fountain: Buy only the missing device or the refill you need. A bundle would duplicate equipment you already use. Skip the bundle and buy the single item.
• If you own a PETKIT litter box: Check the model first. The Crystal Litter Set fits the Purobot Crystal Duo, and the Purifying Liquid Refill fits Pura X, PuraMax, and PuraMax 2. Buy the matching accessory, not a fountain bundle.

Bundle and accessory facts

• EverSweet Max 2 (UVC) Ultimate Bundle: Includes the EVERSWEET MAX 2 cordless UVC pet water fountain plus a 5-pack of filters. The fountain has a wireless UVC pump, dishwasher-safe heat-resistant materials, and a 304 stainless steel tray. The included filter pack means you can maintain the fountain without a separate filter order, and the cordless pump removes exposed wires from the drinking area.
• YumShare Solo 2 + EverSweet Ultra: Pairs the YumShare Solo 2 feeder with the EverSweet Ultra fountain for personalized meal scheduling and fresh, flowing water. Best when you want feeding and hydration managed together, especially if you are away from home for long stretches.
• PETKIT Cleaning Set: Includes 1 brush and 1 sponge, suitable for any cleaning cases, and made of high-quality plastic to prevent rusting. A low-cost add-on that helps keep a fountain operating smoothly, and it is not tied to one fountain model.
• Crystal Litter Set - 4 Pack: Designed specifically for the Purobot Crystal Duo self-cleaning litter box. Absorbs urine and dry solid waste quickly and uses a fragrance-free formula. Only useful if you own the Purobot Crystal Duo; it is not a universal litter refill.

Who each bundle fits

Best for

• Owners who want cleaner drinking water and do not want to order filters separately
• Households that want feeding and hydration handled together while away
• New PETKIT owners setting up a routine from scratch

Not for

• Owners who already have a working fountain or feeder and only need one replacement part
• Cat owners whose main issue is litter odor or scooping rather than water or feeding
• Anyone who has not confirmed their litter box model before buying litter accessories

Pick the bundle that matches the routine you want to fix, not the biggest discount. If you only need one device or a refill, buy that instead. Confirm your litter box model before adding litter accessories.
