I've had cats most of my life and these are the products I've found after much trial and error.
Do you want your cat to look old money rich? This is the only way. We bought it in green and it matches his eyes.
PetSoKoo: Cat Collars
Easy to clean and doesn't absorb smells. You'll never get a plastic box again.
Stainless Steel Litter Box
The coziest for cats or dogs. Easy to wash and super soft.
Best Friends By Sheri Cat Beds & Furniture
This is my #1. I should have bought this years ago. It makes scooping SO easy and doesn't get all gunky. It's strong and doesn't bend. Seriously the best.
Cat Litter Scoop Metal with Hook & Hole
We use this in front of the litter box. Easy to shake out and easy to wash.
Thick Bathroom Rugs
This holds our 20 pounder. He loves it in the winter when it's too rainy and cold to go outside.
Frisco Plush Cat Window Perch - Cozy, Safe Cat Bed with Plush Cushion by Chewy
I've tried them all and we keep coming back to this litter. Easy to scoop, no scent, low/no dust, cat likes it. 10/10.
Litter
This gets the thick undercoat without being too scratchy. A must have for spring.

This isn't hideous and our cat likes it. 10/10
Cat Scratching Posts - Free shipping
God I wish I didn't have to recommend these. Never forget to apply flea meds people! But if you do, get these metal combs, prep a cotton pad with rubbing alcohol, comb through the hair and then grab the flea from the comb with the cotton pad.
Flea Comb
Does my cat like his nails trimmed? No. Does he bite me when I trim his nails? Yes. Anyway, these are good and do the job.
Bark n' Purr Boise
We have hardwood floors and this is the only thing we use to clean any pet messes. It doesn't harm the finish and doesn't leave a smell.
Hard Floor Cleaner
We use it on any laundry that has pet smells and it always gets them out. Get's rid of smells, doesn't just mask them.
