Hi my two 3 month kittens open the zipper of their carrier within few seconds. What to do? How to transport them to and fro vet? Any suggestions please.

Kitten learned not only to open the zipper but how to split the nylon ones so even the soft carriers with locks on the zipper tab were worthless. Hard carrier metal doors.
