Here's what you need to know: 1. For all items I checked, their prices were identical to Amazon/Chewy. 2. They are super nice--the gentleman at the desk combed through all the cat food trying to help me find something without chicken products for my sensitive-tummied Siamese cat, Bernard. We ended up finding an all-fish Orijen dry food and a pumpkin/tuna wet packet from Weruva. Bernard gives PSO 9 stars out of 5 (he's not the best with numbers).

Extremely knowledgeable and kind staff, good selection of products. I'll be coming back here even though it's out of my way.

Absolutely amazing shop! The selection, ambiance, great pet oriented artwork and most of all, the outstanding/incredibly knowledgeable staff are the reason we come back! Thanks for all the help Kate!

Incredibly kind, knowledgeable and just overall genuine and helpful people work here. They have a great selection and I always have a great experience when I shop here. I cannot recommend this place enough!

A great pet store! Their section of cat toys rotates often enough there's always something new for my kitten, and they have a lot of specialty foods/treats I struggle to find elsewhere. Plus their prices are better than most chains!
