The way your said it makes it seem like you think it is a kindness to leave it, it isn’t.
Actually, in many cases the best thing to do is leave the kitten where it is for mum to find - especially when you're not in a position to provide any meaningful long-term care yourself.
You say it’s the reality, then you say in the next sentence “kittens need round the clock care”. So your acknowledging they need care to survive, but say it’s best to leave it on its own.
Yes, as I've clarified multiple times, it's best to leave it alone for mum to find.
It is not best, but it is convenient. There does seem to be a disconnect between the care you acknowledge they need, and your statement that it’s best to leave them uncared for and discarded.
No, that's just your interpretation of my posts. I know OP had good intentions but newborn animals should be with their mum's or in rescue/foster, not with a well-meaning tourist in a hotel somewhere.
I have raised kittens, it’s not rocket science, the kitten might have survived. At least it had some comfort at the end.
Brutally - how would it have survived when OP is on her way back home and had nowhere for the kitten to go? As upsetting as it is, f she hadn't given it to the security guard, it would have been left on the grounds somewhere and died anyway.
It is the reality that animals suffer, but we often can’t help, in this situation the OP could, and did, we need more people like that 😊
But, kindly, she didn't help long-term, did she? She took the kitten away from mum and gave it baby milk and kept it in her cardigan in a hotel room. Kitten was then given to another total stranger who "went to find mum" and who I suspect put the poor thing out of it's misery.
It's easy to say she did a lovely thing and gave the kitten love and cuddles but it didn't need those things - it needed mum or around-the-clock care from a rescue. Not to be put in someone's pocket and fed baby formula.
