6 Month old Leeloo is having some sort of attack. We took these videos to share with her vet. This is the second day this is happening. When she is stimulated with a cat toy, or our other cat gets playful with her, Leeloo snaps out of this behavior and runs around without issue, leaping on and off furniture, as if nothing happened, and all symptoms disappear. The episodes have lasted as long as an hour and a half. We are pretty certain she is in pain from her constant crying. Any information regarding recognition of this behavior would be greatly appreciated.
