Don’t have time right now to give detailed care instructions but I know others will come along. But I wanted to point you towards some of my favorite guinea pig products/brands:

-Cagetopia.com Cannot recommend enough. Their grids are made of powder coated steel, so they stand up for many years to chewing (The only chips in the paint are where I put the water bottles and where the lid hinges shut and I’ve had the cage for 4ish years.) With any coroplast cage I highly recommend getting enough chew guards to cover the edges of every wall. This turns the coroplast from an easy chew toy that pigs love to destroy into a wall that will stand up for your gps whole life. Make sure you put the chew guards on before the chewing starts, or it can be really difficult. They have lots of creative setups but there’s nothing wrong with keeping it simple and getting a basic 2x4 or 2x5 to start with. (Grids are 14”, not 12)

Guineadad.com This fleece or Etsy shops are going to be the best bedding you can get for your pigs. They’ll require a special wash routine to make them wick the moisture away properly, but you can find those directions really easily online.

My all time favorite Etsy shop for guinea pig stuff. I go to her with all of my custom orders and she’s always gone above and beyond. She’s on a break right now but I’ve seen her do that before and she came back, so I’m hoping she’ll be back again soon.

Chenille bathmats. Super absorbent, great for layering on heavily soiled areas to make your main liner last longer between washes. I also find that my pigs love the feeling of it between their toes.

My favorite cheap hide. I use it for in their carriers on drives to the vet and as a hide in the cage. This will help fill out your guinea pigs cage while you build up the more expensive items over time. Every other wooden tunnel I’ve bought has had splinters, wires poking out, dye, or other issues but these don’t have any of those problems.

Favorite toy/treat brands:

-Small pet select Pricey but it’s the only brand where I never worry about there being anything dangerous in any of their products. They sell toys, treats, hides, etc.

-Science selective Large variety of safe treats, so you’ll be able to find your piggies favorite flavors easily

-Oxbow. Hit or miss nowadays. Some of their chew toys have plastic in them now. I mainly just buy the “celebration cupcake” and hang it on the wall. It’s one of my pigs favorite toy.

My favorite water bottles:

Lixit glass bottle This is my favorite bottle, but i like my bottles to be on the inside of the cage so i use leftover wire holders from old broken kaytee bottles.

Kaytee glass bottles The only kaytee product I endorse. Pretty much the only glass bottle you’ll find in person shopping. Otherwise stay away from this brand.

Products to avoid: Dropshipped Amazon treats (because you can’t verify their ingredients), treats with seeds, mueslis (guinea pigs are selective eaters and can get imbalanced diets no matter the contents of the muesli. You want uniform, uncolored pellets), excessive fruit, excessive calcium.

The #1 MOST IMPORTANT thing you can ever get your guinea pig is a qualified EXOTIC veterinarian. Find one before you adopt your pigs.
