My 11-year-old female cat has been behaving strangely after every meal for the past few days.
She eats her food as usual, then she bolts into an empty room and meows very loudly. I usually used to be able to stroke her, but now she just runs away.
She shakes her paws like it's a tic, and sometimes she runs off and starts grooming herself frantically—her back, her legs, and her paws. She usually does this for about 5 minutes. Then she runs around in 'wild and playful' mode (she doesn't seem aggressive), chasing whatever she finds and wanting to go out on the balcony. This lasts for about 5-10 minutes. Then she calms down and comes back to me for a cuddle.
Her diet and toilet habits are the same. She's house-trained and grooms herself often.
Nothing has changed except the fact she goes 'crazy' after meals; she runs away, her paws twitch, and she dashes around grooming herself quickly—always after eating.
Thanks for any help.
