Good catch by Laurie!! I'm very glad you understand why to not re-shoot if you think you gave a fur shot.
The 5 Ps - peeing, pooping, playing, purring, and preening.
Giving any straight protein, as long as it hasn't been brined (brining adds salt and sugar) or cooked with onions or garlic or isn't honey glazed, is fine. I would go easy on the fish, though. Male cats, more often than females, can develop urinary crystals. Fish products are often related to these problems. If you are already feeding Khan canned fish-based foods, I would just be attentive to how much you're giving him.
