Well this has been a very entertaining thread.
Glad you got your cat home OP.
And I’m sure you are worried about the home owners reaction.
They may go apocalyptic at discovering cat piss, damaged paintwork and ham in the
vents and stinking crab sticks - I still can’t believe you actually did that with the ham and forgot to clear up the crab sticks.
If it’s any comfort, something similar happened to us last year, but we were the home owners with an intruder.
We had gone away for a week and my sister sent me a picture of a random cat sitting on our kitchen window.
He was there for 3 days. He was not stuck, He got access through the dog flap and could have easily left at any time.
Then she came across a FB post about a missing cat and so she sent a message and said she was sure it was sitting in an unoccupied house kitchen window.
The cats owners managed to coax the cat back out and when we came home they called to profusely apologise and brought us flowers and wine and offered to clean up any mess left behind.
I declined the offer even though the house reeked and I found cat turds behind the sofa.
I don’t particularly like cats, although OPs is particularly handsome but what was the point in having a go at them about it ? We acknowledged we should have blocked the dog flap up.
Hopefully your neighbours are understanding.
