u/Disastrous-Sleep-434

My male cat, almost 5 years old, neutered seemed to fall off the couch and when he got back up it was as if he lost control of one of his back legs and kept almost falling over. This went on for around 2 minutes and now he's back to walking normally, eating treats and purring away but it has really worried us as it has never happened before. Planning to take him to the vets tomorrow for a check over but just wanted some guidance or advice for the time being. Thank you.
