Getting a cat to take a pill

Ashley

So I went to the vet last night and my older cat Morgan was diagnosed with a respiratory infection. She was prescribed pills to take for it which I put the required amount of in some tuna this morning but she wouldn’t eat it. Tuna is her favorite thing to eat and she is a picky eater. I’m not sure if I should just try again later... idk how to get her to take her medication. Any tips?
