New theory on what happened: My mom said he could have had a seizure and lost movement in his back legs and possibly one of his front legs. He could have not been able to get to food and water for a few days and then just gotten weaker. Now, he also can't go to the bathroom by himself.

He is doing better, eating lots of fresh foods and last night when I had him out while m y dad was getting his food he crawled across my room to his favorite cord that he tries to chew whenever he is out.
