If the medication has been at one a day for a while, it might be a plan to go back to the vet and see whether it needs to be increased.
Mine would have;
Pate - it was how I got the pills down her without any complaint. She knew exactly what I was doing but deemed a ball of pate with a pill centre sufficiently worth the effort. Chicken or pork liver, she didn't mind, just as long as it was pate (and didn't have onion in it - sometimes I cooked chicken livers until they were rare and chopped them up - and I also blended kidneys a couple of times as she got more twig like bork).
Beef mince - again, in little balls.
She really liked the chicken and pumpkin pouches from Applaws.
The tiny (and breathtakingly expensive) Applaws tins (I think Encore are exactly the same but cheaper) of chicken and cheese or chicken, ham and cheese.
Tins of Mackerel in Tomato Sauce. The PDSA and local vet both use it for cats that aren't eating well - whilst raw tomatoes can't be given to cats, the tinned version was fine, apparently.
The webbox pastes.
Anything else she showed interest in, she got. That carried her through the last nine months of her life quite happily until she stopped eating altogether as she was done.
Of course, the other furry residents were incandescent with this preferential treatment, so we had to do it in secret - I'd hold my finger up to my lips as though to say 'ssshhhh' and she'd know to come into the kitchen with me and actually shut the hell up for once in her life as I fed her on the counter under the boiler so the others didn't get a look-in.
It did mean every trip to the kitchen involved a snack for her, though. Which she enjoyed a lot.
However, if she hasn't eaten in a day and isn't hungry the next morning, it's best to make an appointment, as their bodies are either going to shut down from lack of food or it's a sign that they are already moving to end of life.
And if she starts flopping on the floor any time she moves, from experience, it's time to let her slip away rather than trying to syringe the prescribed diet tinned foods into her. (Don't be fooled by the vet suggesting you buy them - most self respecting cats detest them).
Essentially, spoil her rotten and enjoy your cuddles every chance you get.
