If you've spent any time looking for an automatic pet feeder or water fountain, you've probably seen the name "PetLibro" come up a few times in your search. They're one of the most widely bought smart pet brands around, and for good reason—their compact feeders and fountains work great for single-cat households.
When we started designing our own smart gear at Penthouse Paws, we wanted to address the daily frustrations pet owners kept running into with standard feeders and fountains: small hoppers that run out of food in two days, 2.4GHz Wi-Fi setup issues, and tiny water reservoirs that need constant refilling.
If you're trying to figure out which brand makes sense for your routine, here's an honest look at how PetLibro and Penthouse Paws compare side-by-side.

Smart Feeders: Hopper Size, Wi-Fi, and Everyday Reliability
Both brands keep your pets fed on a strict schedule, but they handle larger pets and home network connections differently.
1. Hopper Size & Food Capacity
Most standard PetLibro feeders (like the Air or Granary) have hoppers ranging from 2 to 4 liters. If you have one cat, a 2L or 4L feeder works just fine. But if you have two cats sharing a feeder, or a dog over 45 pounds, those smaller hoppers empty fast.
We built the Penthouse Paws Smart Maxx HD Feeder with a 7-liter capacity. That extra space holds enough dry kibble to last multiple cats or a medium-to-large dog for up to a week. It's also designed to dispense larger kibble shapes (up to 15mm) without jamming.
For smaller dogs (up to 45 lbs) and single cats, our standard 6L LCD Feeder offers plenty of storage without taking up your entire kitchen corner.
2. Portion Control for Medical Diets
If your pet requires a strict diet for weight loss or diabetes management, precision matters. The Penthouse Paws Smart Maxx HD dispenses food in 7-gram increments. This allows you to schedule up to 15 micro-meals a day, maintaining steady blood sugar and healthy digestion without accidentally overfeeding.
3. Wi-Fi Setup and Connection Drops
Both Penthouse Paws and newer PetLibro models support 5G Wi-Fi compatibility. This means faster setup and fewer connection drops if your home router combines 2.4GHz and 5GHz into a single network name.
The Penthouse Paws Smart Maxx HD uses this high-speed 5G connection to power a built-in 1080p HD night-vision camera and two-way audio. That way, when you check in on your pets while away from home, you get a clear, buffer-free stream.
4. Do you want to download another app?
Not everyone wants another app taking up storage on their phone.
Most of PetLibro's products rely on app-based controls. We wanted to make sure owners who prefer physical buttons had a reliable choice. Our 6L Automatic Feeder with LCD Panel lets you program up to six daily meals, adjust portion sizes, and record a 10-second voice message directly on the machine. You get full control with no Wi-Fi or smartphone required.
Water Fountains: Reservoir Capacity and Battery Life
Keeping your pet hydrated is one of the easiest ways to prevent kidney and urinary issues, especially in cats. Both PetLibro (with their Dockstream series) and Penthouse Paws offer cordless, battery-powered fountains so you don't have to place your pet's water bowl right next to an outlet.
1. Reservoir Capacity & Refill Frequency
With a 3L reservoir, PetLibro's Dockstream handles basic daily needs pretty well. But if you hate hauling the fountain over to the kitchen sink every few days, Penthouse Paws bumps that up to 3.5L.
2. Battery Life and Noise Levels
If you like moving the fountain around the house, or taking it with you when traveling, battery life matters. PetLibro's cordless fountains typically run for up to 30 days on a charge. The Penthouse Paws Smart Wireless Fountain includes a rechargeable battery that lasts up to 45 days.
When it comes to noise, both the PetLibro Dockstream and the Penthouse Paws Smart Wireless Fountain operate at a whisper-quiet 23 dB. This near-silent operation is ideal for bedrooms, home offices, and skittish pets that get spooked by the loud motors in older fountain models.
3. Filtration Setup
Any open bowl of standing water turns into a magnet for stray fur, dust, and food crumbs. PetLibro handles this with a standard carbon filter setup to catch floating debris and keep bad smells away. Penthouse Paws goes a step further by layering hollow fiber ultrafiltration alongside the carbon filter—a 5-stage setup designed to trap fine micro-particles, bacteria, and odors before the water recirculates back to your pet.
Which one should you choose?
Go with PetLibro if:
- You have a single cat in an apartment and prefer a very small feeder footprint.
- You already use other PetLibro products and want to keep everything in their app ecosystem.
Go with Penthouse Paws if:
- You have multiple pets, or a dog up to/over 45 pounds that needs a larger 7L food capacity.
- You have a 5GHz Wi-Fi router and want a quick, stable app connection.
- You want an easy-to-use LCD feeder that works completely offline without a smartphone.
- You want a cordless water fountain with a larger reservoir and up to 45 days of battery life.

Frequently Asked Questions
Can I use a 5GHz Wi-Fi network for my smart pet feeder?
Many standard smart pet feeders on the market only support older 2.4GHz Wi-Fi networks. However, the Penthouse Paws Smart Maxx HD Feeder features dual-band compatibility, meaning it connects smoothly to both 2.4GHz and 5G Wi-Fi networks for a more stable, buffer-free connection.
What size automatic feeder do I need for a large dog?
If you have a medium-to-large dog (over 45 pounds), we recommend upgrading to a 7L capacity feeder, like the Penthouse Paws Smart Maxx HD, which holds enough dry food to last up to a week and accommodates larger kibble sizes up to 15mm.
Do I have to use a smartphone app to set up an automatic feeder?
Not necessarily. The Penthouse Paws 6L Automatic Feeder features a built-in LCD panel that lets you program up to six meals a day, adjust portion sizes, and record voice messages directly on the machine without an app or Wi-Fi.
Do pet water fountains have to be plugged into the wall?
No, you can find cordless options. The Penthouse Paws Smart Wireless Fountain and the PetLibro Dockstream are both battery-operated, allowing you to place them anywhere in the house. The Penthouse Paws model features a rechargeable battery that lasts up to 45 days on a single charge.
