My cat is not using the Pipolino® that I put on more than 24 hours ago and I fear for his health because he has not eaten since!

See answer above ‘My cat does not use Pipolino®!‘.

A 24-hour diet and even a diet of several days is safe for a cat, except possibly in case of liver problems and if no food is offered.

Compliance with the proposed instructions for use, with the presence of kibble between the Pipolino® and a wall, avoids this risk.
