Yes, PetPhone is designed for both adult cats and small-to-medium dogs—but not every pet will have the same experience wearing it.

PetPhone weighs 37 grams and attaches to your pet’s existing collar. It is generally suitable for adult cats weighing approximately 3 kg or more and small-to-medium dogs weighing around 4–30 kg or more.

However, weight is only one part of the decision. Collar width, body size, age, temperament and comfort with wearable devices also matter.

This guide will help you decide whether PetPhone is suitable for your dog or cat and show you how to introduce it safely and comfortably.

PetPhone Compatibility at a Glance

PetPhone is currently designed for:

• Adult cats weighing approximately 3 kg or more

• Small-to-medium dogs weighing approximately 4–30 kg or more

• Existing collars approximately 3 cm or 1.2 inches wide or narrower

• Pets already comfortable wearing a collar

• Everyday indoor and outdoor use

PetPhone may not be suitable for:

• Young kittens or puppies

• Very small cats or miniature dogs

• Pets with neck injuries or skin conditions

• Pets that strongly resist wearing a collar

• Collars wider than the recommended size

• Prolonged swimming or underwater use

These are general guidelines rather than guarantees. Owners should always check the individual pet’s comfort during initial use.

Can Cats Use PetPhone?

PetPhone can be used by most adult cats weighing approximately 3 kg or more.

Because cats are often more sensitive to collar weight, movement and unfamiliar objects than dogs, the introduction process is especially important. A cat may need several short sessions before becoming comfortable wearing the device for longer periods.

Before using PetPhone with your cat, check:

• Whether your cat already wears a collar comfortably

• Whether the collar fits securely without being tight

• Whether the device moves excessively while the cat walks or jumps

• Whether the cat scratches at or bites the device

• Whether the device interferes with eating, resting or grooming

A relaxed cat should be able to walk, lie down, eat and move normally while wearing PetPhone.

If your cat freezes, hides, walks unusually, repeatedly scratches the collar or tries to remove the device, take it off and restart the introduction more gradually.

What About Small Cats and Kittens?

PetPhone is not primarily designed for very young kittens or cats under approximately 3 kg.

Even though the device weighs only 37 grams, the same weight will feel very different on a large adult cat and a small kitten. Young animals are also still growing and may be more sensitive to collar fit.

For a very small cat or kitten, wait until the pet is older or speak with a veterinarian before introducing a connected collar device.

Can Dogs Use PetPhone?

PetPhone is designed primarily for small-to-medium dogs weighing approximately 4–30 kg or more.

It can suit dogs that already wear a standard collar during daily activities, walks or outdoor time. The device creates a phone-like connection through the petpogo App, allowing owners to use Two-Way PetChat, receive status updates and access additional safety features.

PetPhone may be particularly relevant for dogs that:

• Spend time with a dog walker or sitter

• Stay in a fenced backyard

• Travel with different family members

• Already understand familiar voice cues

• Regularly wear a collar without discomfort

• Live in an area with supported cellular coverage

The device should remain securely attached without bouncing heavily, rotating constantly or pressing against the dog’s throat.

Can Large Dogs Wear PetPhone?

Some larger dogs may be able to wear the device, provided their collar is compatible with the holder. However, PetPhone is currently positioned primarily for small-to-medium dogs.

Large dogs often wear wider or heavier collars, so owners should confirm that the collar is approximately 3 cm wide or narrower and that the device can be securely installed.

If your dog uses an extra-wide collar, working collar or specialized harness, contact PetPhone support before purchasing.

PetPhone Is More Than Something Your Pet Wears

PetPhone is called a pet phone because it creates a phone-like connection between pets and their owners through the petpogo App.

Its core feature is Two-Way PetChat, which allows owners to speak and listen remotely through the device. Additional functions include location information, safety-zone alerts, activity insights, behavior clues, music and family sharing.

Your pet does not need to understand a screen or operate a traditional phone. The owner controls the experience through the app while the pet wears the connected device.

How to Check Whether PetPhone Fits Correctly

A secure and comfortable fit is essential before using PetPhone regularly.

1. Check the Collar Width

PetPhone attaches to your pet’s existing collar with the included holder. For the best fit, the collar should be approximately 3 cm or 1.2 inches wide or narrower.

Do not force the holder onto a collar that is too wide or thick.

2. Check the Collar Fit

The collar should be secure without being tight. As a general starting point, you should be able to place two fingers between the collar and your pet’s neck.

The correct fit can vary by breed, coat thickness and collar type, so inspect it regularly.

3. Make Sure the Device Is Secure

Before outdoor use, gently move the device and holder to confirm that they will not slide off the collar.

Check the silicone strap and attachment points for wear or damage. A loose device may become uncomfortable or be lost during running, jumping or play.

4. Observe Natural Movement

Let your pet walk around indoors while wearing PetPhone. Watch whether they can:

• Walk normally

• Turn their head comfortably

• Eat and drink

• Lie down and sleep

• Jump or climb without interference

If the device repeatedly hits the pet’s chest, shifts position or changes their movement, adjust the collar before continuing.

5. Check the Skin Regularly

During the first few days, remove the collar periodically and inspect the neck area.

Look for redness, hair loss, pressure marks, irritation or dampness. Stop use if you notice persistent discomfort and consult a veterinarian if necessary.

How to Introduce PetPhone to Your Pet

Do not attach PetPhone and immediately expect your pet to wear it for an entire day.

A gradual introduction can make the experience easier.

Step 1: Let Them Investigate It

Place PetPhone near your pet and allow them to smell or examine it. Reward calm curiosity with praise, play or a small treat.

Step 2: Start With a Short Session

Attach the device to the collar and let your pet wear it indoors for several minutes. Stay nearby and observe their reaction.

Step 3: Create a Positive Association

Use treats, playtime or another familiar activity while the pet is wearing the device. This helps prevent the collar from becoming associated only with restraint or stressful situations.

Step 4: Increase the Time Gradually

If your pet remains comfortable, extend each session. Move from a few minutes to normal indoor wear before testing it outdoors.

Step 5: Introduce the Audio Function Separately

A pet may be comfortable with the physical device but surprised by hearing a voice through it.

Begin at a low volume while you are in the same room. Use the pet’s name or a short, familiar phrase. Reward a calm response before gradually testing the feature from another room or location.

Different Pets May Respond Differently

Dogs and cats do not automatically understand that a voice coming from PetPhone belongs to a person who is somewhere else.

Some pets may immediately recognize their owner’s voice. Others may look around, ignore it or appear confused. None of these responses necessarily means that the device is not working.

Remote communication is most useful when owners set realistic expectations:

• Use familiar words rather than long sentences

• Speak in a calm, natural tone

• Avoid suddenly playing loud audio

• Do not rely on voice alone during an emergency

• Stop if the pet appears frightened or distressed

• Reinforce known cues through regular training

PetPhone can provide a new communication channel, but it cannot guarantee that a pet will follow a remote command.

Can PetPhone Be Worn Outdoors?

PetPhone is IP67 water-resistant and designed to handle everyday rain, splashes and normal outdoor conditions.

It should not be treated as a device for prolonged swimming or intentional submersion. If your dog regularly swims, remove the device beforehand unless PetPhone provides different guidance for your specific model.

Before every outdoor use:

• Confirm that the holder is secure

• Check that the collar is correctly fitted

• Make sure the device has sufficient battery

• Confirm that cellular coverage is available

• Keep identification tags on your pet

• Continue using a leash or secure fence when required

PetPhone’s safety features should support responsible pet care, not replace physical supervision, training or secure boundaries.

How Long Can Cats and Dogs Wear PetPhone?

There is no single wearing schedule that suits every pet.

Some pets are comfortable wearing their normal collar throughout the day, while others need regular breaks. During the adjustment period, use shorter sessions and inspect the neck area frequently.

PetPhone should also be removed when:

• The device needs charging

• The collar or holder is damaged

• Your pet shows signs of irritation

• Your pet is swimming or being bathed

• A veterinarian recommends removing wearable devices

• The collar could become caught during unsupervised play

Comfort should always take priority over continuous data collection.
