They can't tell you when something's wrong. That's why the small things matter — and why they're worth writing down.
Petla is a health journal for dogs and cats. Thirty seconds a day: log appetite, energy, and bathroom habits. You'll catch changes early — and along the way, without trying, you'll build a record of your life together.
WHAT YOU CAN DO WITH PETLA
Daily health check in 30 seconds
Just tap to log appetite, energy, and bathroom habits. Simple enough to actually stick with, even on busy mornings.
See changes at a glance
Weight and appetite are charted automatically. Subtle shifts from a few days ago become easy to spot.
Walk into the vet prepared
Show exactly when symptoms started and how they've progressed, instead of trying to remember the details.
Never miss a vaccine or medication
Set schedules once and get reminded before they're due.
Keep the whole family in sync
Share your pet's records with family, even if you live apart. No more guessing who fed them last.
AND WHILE YOU'RE DOING ALL THAT, SOMETHING ELSE HAPPENS
Add a photo and one line a day
"Stopped under the cherry tree on our walk." That's enough. It seems like nothing today. Someday it will be everything.
Watch the days add up
Petla counts the days you've spent together — and at the end of each month, it turns your photos into a single picture worth sharing.
Old days come back to visit
Open the app on an ordinary morning and find a photo of your pet from a year ago today.
And if the day ever comes to say goodbye
Petla gathers your photos, notes, and numbers into the story of a life — one you can keep, print, and return to whenever you miss them. This part of Petla is free. Always.
PETLA IS A GOOD FIT IF YOU:
Are busy, but want to notice small changes before they become problems
Have more than one pet and want to track each individually
Want the whole family looking at the same records
Believe ordinary days are worth keeping
Because they're family. And the little things matter.
Start with today. It takes thirty seconds.
