First 30 Days Checklists: A Species-by-Species Quick Reference

The first month with a new animal packs the most decisions into the least time. Here are short checklists for a dog, cat, rabbit, guinea pigs, a backyard flock and an aquarium, made to print or screenshot. Each links to the full guide that explains the why.

The one-glance overview; the checklists follow below.

First 30 days at a glance, by species
Species	Week one	By day thirty
Dog	A crate or settling room, a toilet routine, a vet check	Basic manners, gradual access to the house
Cat	One safe room with litter, food and hiding spots	Gradual introductions, wider run of the house
Rabbit	A rabbit-proofed space, a companion plan	Daily time out of the enclosure, a vet visit
Guinea pigs	Cage, hides, and a companion from day one	A handling routine, a vet check
Flock	Secure coop and run, feed and water routine	Supervised free-ranging, integration if joining a flock
Aquarium	Cycle the tank before any fish	Add fish gradually, regular water tests

Dog and Cat

One easy-to-clean room or crate area at first.
A steady toilet routine from day one.
A vet check in week one; microchip details registered in your name.

Vaccinations, worming and flea or tick prevention for a new pet: see your vet or a pet supply store with trained staff. Bring any records from the shelter or breeder to the first visit.

Rabbit and Guinea Pigs

Rabbit:

Rabbit-proof the space first: hide cables, protect skirting boards.
Plan for a companion; rabbits are social.
Book an early vet visit with a rabbit-savvy vet.

Guinea pigs:

Set up the cage with plenty of hides before they arrive.
Keep at least two together from the start.
Build a short, gentle handling habit.

Flock and Aquarium

Flock:

Predator-proof the coop and run before the birds move in.
Set a feed and water routine on day one, with no kitchen scraps.
Check whether you need to register your birds; rules differ by country (in Great Britain, all poultry keepers must register with APHA).
Introduce free-ranging gradually and under supervision.

Full guide: starting a backyard flock.

Aquarium:

Cycle the tank fully before a single fish goes in.
Keep the filter running all the time.
Add fish a few at a time once the tank has cycled.
Test the water every week at first.

Frequently Asked Questions

Questions from people using these lists for real.

Do these checklists replace the full guides?

No. Each one links to a fuller guide with the reasons, timing and common mistakes. This page is the quick version for a mid-week check.

What about a pig or goats?

Farm animals come with land, fencing and legal steps that need more than a checklist. Start with smallholding setup and the species page.

Can I print just one checklist?

Yes. Each species has its own short block, so print or copy just that part.
