The monthly cost of a cat will vary based on their age, breed, size, medical conditions and how much you want to spoil them. You’ll need feeding supplies, bedding, cat scratchers and trees, toys, litter and a litter box, as well as veterinary care when necessary. General estimates for the monthly cost of a cat range from $50 to $80 but can easily be higher than that if you want to buy them the best supplies and solutions available. And while some cat expenses—like vet bills—are tough to avoid, Petco’s cat deals can make it easier for you to discover cheap cat stuff without sacrificing quality.
