My cat will be 21 years old this month. She has recently started having seizures a few times a week. She has developed a twitching in her legs and can't stay still long enough to sleep or eat. I have to hold her on my lap to feed her. She walks around the house aimlessly all day long. I hold her a few times a day to give her a rest and she will only sleep for a few hours when she's absolutely exhausted. Can I give her anything to stop the leg twitching?
