I keep the carriers out and open (cat caves) most of the time. Livvy is more apt to use them as retreats than Cassy. Note: I believe she uses them as a retreat FROM Cassy when he's off-the-wall weird, but it's hard to tell with cats...

The tilting it to "face the ceiling" and lowering cat into it is about the only method I've been able to use in quite a while. The 'special treat in the carrier' trick only worked when they were very little kittens.

We occasionally go 'outies' to drive-throughs and get bacon or a plain shreaded beef sandwich (spoiled fur-kids? no!....) which makes the carrier a LITTLE less obnoxious.

Ejecting the kids at the vets is a struggle and I've had cause to bless that the carriers disassemble.
