Vivarium Keeper
The reptile husbandry logbook your spreadsheet was pretending to be
A profile per animal, then log feedings with feed response, shed cycles, weights with a growth curve, and enclosure temps and humidity scored against 16 bundled species care sheets. Everything unlocked, nothing installed.

What you can do in Vivarium Keeper on the web
A profile for every animal
Name, species, morph, sex and acquired date for each ball python, leopard gecko, crested gecko, tortoise or custom species — no two-animal limit.
Feeding log with feed response
Prey type, item, size and whether it ate, refused or regurgitated. Two refusals in a row and the animal is flagged on the home screen and its feeding log.
Shed cycles, start to finish
Mark the day it goes opaque, mark the shed complete later, and see the average cycle length and shed quality (complete, patchy, retained eye cap).
Weights and a growth curve
Log weights in g, kg or oz; the curve, total change and per-weigh-in delta build themselves so a quiet weight loss is obvious.
Enclosure readings vs care-sheet targets
Warm side, cool side, basking, ambient and humidity are drawn on a target-band gauge from the species care sheet, with a humidity trend chart.
16 bundled care sheets
Temps, humidity, diet, feeding cadence, enclosure size and keeper notes for the common pet species — searchable, and wired to every animal you keep.
Breeding and clutch records
Pairing, ovulation and lay dates with clutch size, fertile, slug and hatched counts, plus a hatch rate across every clutch.

You can start fresh at any time.
