your cat understands I promise! Those feline friends of ours have that extra sense, she knows you didn't mean to do so! I have done the same to my boyfriend's cat. He looked pretty scared of me as well, he was genuinely trying to get out of my way but the 'zombie wobbles threw him off and he couldn't tell what direction to run for, lol, poor guy.

I say our feline friends understand because the same cat always comes to find me when im feeling my worst. Its like a radar to him, he climbs up on the bed and cuddles me as close as he can.

Don't let your pride be bruised by this. Your kitty will always be by your side no matter how many times you fall on them, step on them, or try petting their head and you perception is so far off you give them a good whack in the nose/face area (I had to start petting jinx with my left hand because I could never get my right hand to gently pet him and he looked terrified everytime id go to pet him)
Lol. They're our buddies and will ALWAYS be there for us =)
