Update:
Pippin wouldn't leave his wound from being neutered alone and so he has been kept in longer to make sure this healed - he was also made to wear the 'collar of shame' to keep him away from it! Collection was re-scheduled for tommorrow.
However, about an hour ago I had a phone call from the centre to say that his scar is now infected, he's on antibiotics and so he won't be released until he's seen the vet next Tuesday.
Add this to my impressively bloodshot left eye which has appeared from nowhere, plus our lovely Siemens Porsche kettle that I dropped and broke last night and it's not been a good couple of days!
