I may be being far too precious-first-kittens 🤣 but just wondering.... sibling boy and girl kittens, nearly 5 months, boy cat can be castrated this month, they will do girl cat separately in Dec/Jan.
So when boy kitten goes in, this will be the first time they've been separated and also he'll come back smelling 'of vet'...
Are there any potential issues with reuniting them, like girl kitten not accepting him back because of the vet smell?
