Clearly that cat hates her harness and doesn’t want to go outside

“Cats don't get used to new things quickly. Just be patient. Many cats respond like this at first.”
“I bought her a harness so she could go outside. Just dead legs it.”
“My cat sits by the door now to tell me to put on harness. Even with the rig, if left alone he tries to catch birds! Little monster.”
