I received these products for free from the Spotted by Petco sampling program in exchange for my honest review. I have four male guinea pigs who's sizes vary do to age and breed. I knew none of my furbabies would like the costume (since every pig I've had in the past has hated them), but honestly this was more for me than for them. I tried it on my biggest boar first, but it didn't fit; that didn't surprise me though since he's a a fluffy monster and I swear his hair adds and extra couple inches to him. Next was my chunker, Bacon. Nope. Couldn't get it to fasten around his big ole belly. Then Bacon's brother, Pancake, was next. It fit him, but was clearly very tight and he was extremely uncomfortable. Finally was my youngster, Porky Pig. Success! It fit him perfectly! He didn't like it clearly, but he was able to stay in it long enough for me to take some silly photos and that's all I wanted honestly. So if you have full-grown plump male guinea pigs this probably won't fit them, but smaller younger males or possibly females I'd recommend it. It's worth it for the laughs and memories alone.

Blizzard wasn't totally thrilled about being a "bacon taco", but all of us humans loved her in this costume! It fit perfectly, and it was easy for us to put on and take off with the velcro, but not possible for Blizzard to wiggle out of. I would absolutely recommend this costume for your adult sized Guinea Pig!

Super cute Halloween costume that fits my guinea pig. He is able to move around and the strap is adjustable. I love the designs on it and he literally looks like a taco. He looks adorable and ready to show it off.

I got this for a guinea pig but it's roomy and adjustable enough to fit on a small dog or cat. The bottom velcro strap adjusts quite a bit, 3" to 5". The front also has a velcro strap, 2" to 4". To top off the cuteness, it's really soft.

I received this product for free in exchange for my honest review. This is the most adorable pet costume I’ve seen in a long time. The costume is very soft and the separate neck and belly straps make it super easy to put on and remove. Every pet can be a taco in this costume! It is a good Guinea pig size, too big for my little hamster, but my cat happily modeled.
