New Puppy & Kitten Supplies Checklist: What You Actually Need

The pet store wants you to buy everything; your new pet needs surprisingly little. Here's the honest split — with the printable PDF version to take shopping. Shop the must-haves first, bring your pet home, and let a week or two of actual living tell you what to add — a new pet reveals their real preferences fast, and buying blind before that just fills a closet with unused gear.

Puppy Must-Haves

Full setup walk-through in the First 30 Days guide.

A few category notes worth knowing before you shop. Crates should fit your puppy's adult size with a divider panel to shrink the space while they're small — one crate that grows with them beats buying twice. Collars vs. harnesses: a well-fitted harness is gentler on a growing puppy's neck and trachea for daily walks; keep the collar for ID tags and save leash-clipping for the harness, especially with small or brachycephalic breeds. Food: don't switch brands on day one even if you plan to eventually — sudden diet changes cause stomach upset on top of an already stressful transition; transition gradually over 7–10 days once your puppy is settled.

Kitten Must-Haves

Setup details in the first week with a kitten guide.

A few notes here too. Litter boxes: buy two even for one cat, and skip scented litter — most cats actively avoid it, which is a fast route to litter box avoidance elsewhere in the house. Full guidance in the litter box training guide. Scratching posts: buy tall and sturdy from day one rather than a cheap starter version — a wobbly, short post gets rejected in favor of your furniture almost immediately, and retraining later is harder than buying right the first time. Carriers: a top-loading or easily-removable-lid carrier makes vet visits dramatically less of a wrestling match, especially once your cat is fully grown and opinionated about it.

Skip for Now (Buy Later, If Ever)

Fancy beds before you know their sleep style, clothing, automatic feeders, water fountains, GPS trackers, the fourth through fourteenth toy, and breed-specific grooming tools before a groomer shows you which one you actually need. Every dollar skipped here funds the emergency cushion that matters more.

None of these are bad products — they're just premature. A water fountain matters more once you know whether your cat is a fountain cat (many are, some genuinely aren't). An automatic feeder matters once you have a settled feeding routine to automate. Buying the upgrade version of something before you own the basic version just means storing two of an item you needed one of.

Don't Forget the Non-Shopping List

Vet appointment booked for week one, after-hours emergency clinic number saved, home pet-proofed, household rules agreed (furniture? bedroom? cue words?), and the first-year budget sanity-checked.
