panic in his eyes

Just a suggestion, but until he is completely 100% himself, I would forgo introducing him to another cat. You want to keep his stress level as low as you can to keep him on the road to wellness.

Also there is a danger your other cat might catch his cold.

I am very happy that your guy is back home with you . I hope he is getting well soon
