Any of those are possible, but I don't think so. I believe she got a catnip seed or stalk stuck in there yesterday morning. Either in her mouth, between teeth or in her throat. She was perfectly fine up until she nibbled at the Catnip Bar. All heck broke loose immediately after that, she was pawing at her face badly after she tried to eat her second breakfast meal and things got worse until last night she would not even allow me to feed her and growled at me when I tried.
It's gone now. I was praying all day at work, and all night in my sleep. And she was pulling Reiki from my friend who is an Animal Reiki practitioner. The prayers and the Reiki energy did the job, helped whatever it was shift, and she is better now.
