"Free shipping made the decision easy, and the quality did not disappoint at all. I had a small issue with sizing but their customer service was excellent, no hassle getting it sorted out. Genuinely one of the smoothest shopping experiences I've had, will definitely be ordering again!"

Meet Your Pet's New Favorite Cozy Outfit

Make chilly days more playful with this Cozy Monster Hooded Pet Onesie. Designed for cats and small dogs, its turquoise-blue plush fabric, purple spots, rounded back spikes, hood, and decorative tail create a fun monster-inspired look for supervised indoor lounging and seasonal photos.

  • Soft plush comfort: A fuzzy plush texture makes a cozy clothing layer for cooler indoor moments.
  • Four-leg coverage: The onesie covers the torso and legs while leaving paws uncovered.
  • Monster-inspired details: Purple spotted pattern, rounded 3D back spikes, a hood, and a decorative tail.
  • Ribbed sleeve cuffs: Turquoise cuffs provide a neat finish around the leg openings.
  • For cats and small dogs: Choose from XS–XXL using chest and back-length measurements.

Size Guide

Measure your pet's chest circumference at its widest point and back length from the base of the neck to the base of the tail. Measurements should take priority over weight; if your pet is between sizes, consider sizing up for a comfortable fit.

Size Chest (in) Back Length (in) Suggested Weight (lb)
XS 11.8 7.9 2.2–3.3
S 13.8 9.8 3.3–5.5
M 15.7 11.8 5.5–7.7
L 17.7 13.8 7.7–9.9
XL 19.7 15.7 9.9–12.1
XXL 21.7 17.7 13.2–16.5

Measurements may vary by up to approximately 1.2 in. Check that your pet can walk, sit, and rest naturally; remove the outfit if your pet appears distressed, overheated, or restricted.

Care and Use

  • Introduce clothing gradually with short, supervised sessions if your pet is new to garments.
  • Keep the hood away from the eyes and never force a pet to wear it.
  • This is a cozy clothing layer, not a substitute for proper shelter or protection in extreme cold weather.
  • Follow the garment care instructions supplied with the item; gentle handling helps preserve plush texture.

Customer photo review of Double-Decker Convertible Wheeled Travel Carrier

Great, I chose the whole set, and it's of very good quality. ☺️ . I'm just going to replace the bottom (in the plush cover, there is a very rigid cardboard, I really appreciate this recycling by the way). ), because my cats often have "leaks" during the journey, due to a hard plastic bottom. In my photos, it was assembled quickly; the second one looks loose, but when the steel bars are properly in place, the fabric is well stretched, so rest assured... arrived 1 month before the scheduled date .. I highly recommend this item, as well as the seller.

Customer photo review of Waterproof Quilted & Non-Slip Sofa Cover (Fitted)

I find the quality really great and it doesn't smell like chemicals at all. It's a bit larger than the area I wanted to cover, but you can easily tuck it into the crevices, so it only becomes noticeable if you look closely. Absolutely recommended for use as a dog blanket.

Customer photo review of Waterproof Quilted Oxford Non-Slip Car Seat Cover

I am really delighted with this purchase. It fits perfectly with another X3, the small space for the seat belts is great, and we were able to travel with our little dogs comfortably.

I had a question before ordering and customer service was incredibly helpful and quick to respond. My order arrived sooner than expected and the quality was honestly better than I anticipated. Everything from ordering to delivery was smooth. Really happy I found Tail Unity!

Finally found a dog gate that my dog can’t constantly shove around. It feels heavy and well made, but still looks nice in the house. Installation was simple and the door is really convenient when I’m carrying something. Exactly what I needed for the bottom of our stairs.

Chloe B., Austin, TX

Our Labrador completely took over the new dog bed on the first day. He has plenty of room to stretch out and seems much more comfortable than he was on his old bed. I especially like that the cushion can be removed for cleaning. It’s become his favorite spot in the house.

Car rides used to be a struggle because my little dog would move around the entire back seat. Now she has her own spot and actually settles down for the drive. The cushion is soft, the seat feels secure, and getting it set up was really easy.

Michael R., Mesa, AZ

Traveling with two cats has always been a pain, so having separate compartments has been a game changer. I can roll the carrier through the airport instead of carrying everything, and the wheels move really smoothly. Both cats had enough room to stay comfortable during the trip.

Samantha L., Tampa, FL

I work unpredictable hours, so keeping my cat on a consistent feeding schedule wasn’t always easy. The automatic feeder has taken a lot of stress out of that. Meals are portioned out on schedule and I don’t have to worry about rushing home just to feed him. Such a useful addition to our routine.
