With Tigris we do it the exact same way as Lorraine with some added protection: Siegmar gets Tigris between his knees and he has garden gloves Plus I put the pill in liver pate and give it between Tigris' sharp teeth with the end of a long icecream spoon
Our Tigris is not the most intelligent of kitties (sorry Jazz- but you better know that about your bf ) so he always could be lured in the kitchen with some treats. I have no idea how you could do it with Filou who is much cleverer and you ahve to know one trick more than him which is not easy.

I wish you all good luck with poor Ripley.
