Sometimes I have had to delay an expected meal to
lure a kitty into the carrier for treatment. After she's
waited some hours pass the normal feeding time, give
her some canned food inside the carrier. Push it to the
back and be ready to close the door when she goes in.
It's really a balancing act on your part, as you have to
actually act like "nothing special" is going on.Just keep
in mind how this will help her, and no matter what happens
try to keep your voice, soft & sing-song like. Best of Luck.
I know you can do it, and she'll thank you for it later.
