I was also thinking that you could mix the pill powder into a liquid. If Tiger likes it then he can drink it and if he doesn't then maybe you could put it in a syringe and then try to squirt it down his throat. Hopefully this wouldn't cause a gagging reflex in him. I sure hope that something will work and that he'll start feeling better soon. He looks good in the video. Your grass sure is getting long. Do the cats ever try to eat it?
