I adore his store! It is very much a dog oriented store, but they also have a small but excellent cat section. This is a good thing because I don't actually own a dog..
There is a wall of canned cat food. All very wonderful brands with good ingredients. They have deals where you can get a percentage off if you buy many cans at one time. Basically fill a cardboard tray and you're set! I personally buy Weruva, and Petagogy has every flavor imaginable. They also have two sizes. It's very much a whole foods for pets in a way due to the natural ingredients in the brands they stock. There are also cat toys, trees, treats, tunnels, beds, catnip and plants, litter pans and leashes/collars.
It can be a little on the more expensive side, but for good reason. The products are excellent and worth it! The customer service is also great. They have a customer card that can give you deals as well if you frequent.
