I'll definitely let everyone know the outcome.
I was almost scared to open my eyes and look at her this morning, I was so afraid there might be a dead kitty next to me in bed
But she hasn't gotten any worse since last night. She is still wide awake and alert, she even tries to bat at her toys. The first thing she did when we woke up was eat. I don't normally feed my cats right when I wake up, but she was meowing at her bowl, and I figure if she has the appetite while she's sick, she can get food whenever she wants it. So she's eaten, drank water, peed and pooped, walked around and batted her toy feebly, and is now licking up the leftovers from her bowl in the 15 minutes that we have been awake. I'd think that if it was something internal that was causing all this pain, she wouldn't be too keen on eating and drinking. She doesn't seem really weak or lethargic. She's doing her normal morning routine, just with a limp.
She's still gimpy. I almost want to take a video of it. She'll stand with her back kinda hunched up and tense, and then she'll hobble with her back right leg moving very stiffly. While she was laying down for bed last night, I was scratching her and she was purring. I took the opportunity to poke and prod a bit to figure out where the pain is. I could lightly pet down her back, but if I pushed too hard, she'd meow. If I lifted her right leg (she was laying on her side), she would meow. If I squeezed her right toes or foot she wasn't bothered. If I got anywhere near her tummy she would meow. Picking her up is painful for her. The incision is still clean and healthy. If she does have an infection, it's internal somewhere.
I just can't imagine what this would be. I was kind of wondering if injury was possible. But she started to show symptoms two nights ago. I picked her up and she meowed which is very atypical. I called her a grump and blew it off
She seemed normal all day yesterday, running for food, jumping, etc. I was with her all day also, and I never saw a fall from furniture or anything (I don't have any high furniture to jump from). It was just almost instant, around 4pm. She went from being normal to meow/growling anytime I picked her up and limping around.
