That was a bit of a disaster of a morning.
To start with, Tobias escaped from the room when I opened the door a crack to check on him, took me half an hour & chicken to tempt him back in. He then ate only a very small amount of the fresh tuna laced with Gapapentin - at least he'd eaten the entire lot last night.
Bit of a pain to catch, he wasn't charging around or anything but wedged himself under some racking in the corner of the room & hung on for dear life.
He WAS very good at the vets, just lay there in the scales pan & leaned into me scratching his head & neck while we talked. She took him downstairs to try to get bloods done, but when we came back he'd let her shave his neck but no more. They couldn't fully sedate him because he'd eaten a bit in the morning, in case he threw up (standard practice there).
So we now have a dilemma. To get the Gabapentin in him, the only way is in his food. But he can't eat for 12 hours before the full sedation, so there's no way I can get him drugged up in the morning. The 2 options are either get him drugged with Gabapentin in the early afternoon so we can get him to the vets before 5pm that day. He would then stay there overnight (not attended overnight there) so he was there & ready for them in the morning. The other option is drug him & shut him in the bedroom the night before the appointment and between the 2 of us not let him escape & catch him with less gabapentin in him.
The safest way to ensure all goes well would probably be option 1, but that would be much more distressing for him as at least at home he's in his own bedroom with familiar beds, toys, smells etc. He would also be gone nearly 24 hours as opposed to just a few if he was at home overnight.. Girlcat would also get quite distressed at him being gone for that long, she's quite unhappy as it is with him shut away overnight. I would also find it rather upsetting him being away in an unfamiliar place that smells of vets & meds overnight.
The risks of option 2 are if he escapes again in the morning, or we can't catch him as he's much less drugged than normal. There's a number of mitigations we can take around that - shut every door in the house so even if he gets out of his room he can only go in the hallway & stairs. With 2 of us we should be able to chivvy him into a corner. I can also block off the bottom of the racking in their bedroom.
I think we need to go for option 2.
