I do too!!!! His limp is worse when he has been laying down for a while. Poor baby! I will monitor him today and if it gets worse, I guess we will go to the vet again tomorrow. I just know that he is tired of being poked and prodded.
I don't know about Charlie horses....but when Vegas has a violent seizure, he limps for days. His muscles are over tensed during the episodes and little boy is so sore days after.
