Charlie, my moggy boy, was diagnosed last week with an over-active thyroid which has caused HCM. He's on diuretic tablets (quarter tablet) twice a day and has to take 1 thyroid tablet once a day - its Vidalta he's on. He's also to get a quarter aspirin 3 times a week incase of blood clots. We have no problems with the diuretic or aspirin as they are small enough to hide in a bit of a prawn and he doesn't notice them. The Vidalta ones are bigger and he is becoming wise to them being hidden in prawns and spits them out and eats the prawn. They can't be crushed or split as they're slow release. The vet has said not to get him stressed out, but the only way to get him taking the thyroid tablet today was to use a pill popper - he wasn't too fussed when we did that and it only took seconds. Probably better for him than getting prawn after prawn with hidden pills. Does anyone have any hints or tricks for giving cats pills?
