Dreams of a Cheetah (the feline version) is sick!

My username came second, the cat was named first.
So my little buddy has been sleeping more than usual and has been doing a kind of sneeze/cough. Mrs. Cheetah and I are both pretty sick, and are worried he caught it. So we ordered some cat medicine online and got it today. It’s in pill form, and we’re not sure how to give it to him.
Dreams of a Cheetah has been eating dry cat food that has a picture of himself on the bag. But reading about how most pet food provides the bare minimum of nutrition and causes a lot of kidney problems, we decided to give him something healthier to eat. I’ve noticed that some grocery stores now have a small fridge in the pet food section that contains refrigerated food. We got him some moist cat food, and he’s mostly just been nibbling at it.
Crushing up his cat pills and mixing them with his wet food means he won’t take all the meds, and we’re not sure what to do at this point. We want to be good humans and take care of him.

How old is he?
Our felines are part of the familly and get Full Medical care as such.

Don’t ask us, get him to a qualified veterinarian ASAP!

Yeah. Good luck to humans & critters.

But you both need professional help, not well-meaning internet strangers. And the crew here may be almost universally well-meaning but we’re also really stranger than most.

Good luck & let us know how it goes.

Yep. Changing the food rarely works for a sick animal. (short term)

Cats are not just sick, they are “very” sick when you notice it.

Cannot say it loud enough: Go to the Vet!!
