Frankie's op was fine. They made a tiny cut to snip the bits but it didn't need stitches. They shaved a bit off his leg for injections and his little bits were shaved which I knew they would otherwise there would be no way they could find them! Silly fur ball.
When they brought him out in his carrier he was very sleepy, sad and scared. He looked way too cute. When he realised I was there he started crying for me. Had to spend the trip home with my fingers in the carrier so he could cuddle to them otherwise he meowed so loudly.
When we got home I let him out and he was very wobbly, sore and incredibly thirsty. After a good drink he came and cuddled up with me for a big sleep.
Later on in the evening I gave him some chicken which he wolfed down. He kept trying to have play but falling asleep. After a lovely night of cuddles he was back to normal (if not more hungry than normal) on Saturday.
In short, getting Frankenstein snipped resulted in lots of cuddles and hopefully him not want to go far when I start letting him out. Bonus :D
