The first week with a new puppy or kitten is chaotic, joyful, and exhausting in roughly equal measure. Most of the problems first-time owners run into — accidents all over the house, sleepless nights, a pet that won't settle — are predictable and manageable if you've prepared. Here's what to have ready before your new pet comes home.
Before They Arrive: Vet Setup
Book a vet appointment before you bring your pet home, not after. Most vets recommend a new-pet exam within 48–72 hours of adoption to establish baseline health and catch any issues before they become serious. Finding a vet you like, confirming they're accepting new patients, and having an appointment scheduled removes one stressor from the chaotic first days.
Ask the vet about the vaccination and parasite prevention schedule appropriate for your area. Flea, tick, and heartworm prevention varies significantly by region.
The Essential Shopping List for Puppies
- Crate — sized so your puppy can stand, turn, and lie down comfortably but not much bigger (too much space encourages using one end as a bathroom). Wire crates with divider panels are cost-effective as the puppy grows.
- Puppy-appropriate food — ask the shelter or breeder what they're currently feeding and get a bag to transition from. Sudden food changes cause GI upset in puppies.
- Food and water bowls — stainless steel is easiest to keep clean; avoid plastic, which harbors bacteria.
- Collar and ID tag — with your phone number, before the first day. Microchipping at the first vet visit adds an additional layer of safety.
- Leash — a 4–6 foot flat leash for training. Retractable leashes don't teach loose-leash walking.
- Baby gates or exercise pen — to limit access to the house until housetraining is solid.
- Enzymatic cleaner — for accidents. Standard household cleaners don't fully break down urine odor, and dogs will return to spots they can still smell.
- Chew toys and interactive toys — puppies need to chew. Give them approved outlets or they'll find their own.
- Training treats — small, soft, and smelly. You'll go through a lot of them in the first months.
The Essential Shopping List for Kittens
- Litter box — one per cat plus one extra is the standard rule. For a single kitten, two boxes in different locations reduces accidents. Covered boxes retain odor and some cats dislike them; open boxes are generally preferred.
- Litter — unscented clumping clay is what most cats prefer and what most experts recommend for kittens. Scented litters often deter use; so do pine or crystal litters until the cat is accustomed to them.
- Scratching posts — cats scratch to maintain claws and mark territory. Horizontal and vertical options both work; sisal rope is popular. Post height matters — it should be tall enough for your cat to fully stretch.
- Cat carrier — hard-sided carriers are safest. Get your kitten used to it before the first vet visit by leaving it out with bedding and treats inside.
- Interactive toys — wand toys, laser pointers, puzzle feeders. Kittens need active play; a bored kitten is a destructive kitten.
- Food and water bowls — wide, shallow bowls reduce whisker fatigue (a real thing — cats dislike their whiskers touching the sides of a bowl).
- Age-appropriate food — kitten food has higher protein and calorie density than adult food. Feed kitten food until around 12 months.
The First Night
The first night is the hardest for most new owners because the pet cries. A puppy separated from their littermates and put in a new crate alone will often cry for hours. This is normal. What's not helpful: going in to comfort them every time they cry, because that teaches them that crying works. What does help: placing the crate in your bedroom so they can hear you breathing, putting a ticking clock or low-volume white noise near the crate, and using an item with their littermates' or mother's scent if you have one.
For kittens, set them up in one smaller room first (a bathroom works well) rather than giving them the run of the house. Overwhelming a kitten with too much space leads to hiding and accidents. Let them explore the house gradually over the first week as they settle in.
The First Month: What to Expect
Housetraining a puppy takes most owners 4–12 weeks of consistent effort. "Consistent" means taking the puppy out immediately after waking, after eating, and after playing — approximately every 1–2 hours during the day. Crate training is the most reliable approach because dogs instinctively avoid soiling their sleeping area.
For kittens, litter training is usually faster — most adapt within a few days if the box is clean, accessible, and not adjacent to their food. Cats prefer privacy; don't put the litter box in a high-traffic area.
Budget for more vet visits in the first year than you may expect: puppy and kitten vaccines typically require 3–4 visits spaced several weeks apart. Building a vet relationship early and getting ahead of parasite prevention makes everything easier down the road.
