Oliver Sprout!
In the approximately 7 years we have had him, he's never had to go to the vet (fingers crossed it continues that way)
He needed to have a wormer tablet. I took it out of the blister pack, put it on the floor in front of him and......*he ate it!*
I will admit I was very pleased, he's a big chap and I didn't fancy my chances with regard to wrapping him in a towel and forcing it into his mouth.
On the down side, he has wrecked the only net curtain in the house, at our bedroom window by burrowing under it and the roller blind so that he can keep an eye on what might be going on outside.
Other window sills are available but
I've got another 'keen'... Ouch!
