Tablet on work top, small blob of butter/marg next to it.
wrap cat in towel ( all in swift moves - put towel over cats back, head sticking out, quickly wrap towel under and around cat quite tightly ) basically swaddle him like a baby. Cat in arms - like a baby, use index finger, scoop up butter, press it on tablet to pick it up. Other hand, or someone else, get hold of cat in corners of mouth and open mouth, buttery tablet on back of tongue , hold mouth shut , massage throat, til cat swallows. Works every time for me......good luck. Dogs are far easier. Lol
