The useful bit
One bowl.
Zero mystery.
Open Catter, pick the cat, and leave a small receipt. The next person sees the answer before another scoop lands in the bowl.
Mochi
Leave the next person an answer.
This is only a local demo. Try the interaction—nothing is saved or sent.
How it works
Good care leaves a receipt.
Fast enough for the kitchen. Clear enough for a sitter. Quiet enough that feeding the cat does not become another conversation to manage.
Doctor Pupa asks the difficult question.
“Did you feed your cat, sir?” Submit to a completely unnecessary medical examination.
LOGGED
02Lawyer Pupa objects to the evidence.
Breakfast is hearsay. The portion was tiny. The defendant requests an immediate appeal.
SEEN
03Detective Pupa follows the crumbs.
An empty bowl. A timestamp. A suspiciously hungry witness. Solve the breakfast mystery.
CASE CLOSED
Built for real households
The cat does not care whose shift it is.
Partners, roommates, family members, sitters, and two-home routines all need the same thing: a trustworthy answer about what already happened.
The end of “did you?”
Feed the cat.
Leave a receipt.
Catter is a lightweight shared log for ordinary cat care. Free to start, private by default, and no smart feeder required.
