And be careful and make it a two person operation (one person holding cat, one administering stuff). Eighteen-gauge IV needles are sharp as death, can penetrate flesh like buttah and hurt like f00king hell.

Ferg was so calm and kind that I tried to do it by myself on a day when the others were out and about for the evening. He moved just a little as I was trying to put the needle in. Had to leave a note that all the blood had nothing to do with the cat and I'd clean it up when I got home.
