This cat takes sleepwalking to a whole other level.<br /><br />Filmed and shared to Twitter by her owner, Debbie Martin, this video shows her cat Jackson fast asleep and moving his paws back and forth rapidly, as if breaking into a run.<br /><br />The sight scared Martin, who thought he might be having a seizure, so she called a veterinarian to ask for advice.<br /><br />"Night vet asked me to email her the video+she just called back to say he’s fine+is just chasing something in his dream," Martin tweeted. "He’s never been this lively in his sleep before!"<br /><br />This video was filmed in Bath on June 21.
