Lets start at the very beginning...
I had 3 rescue kittens. Last summer one went missing (I live pretty rurally) and I distributed posters, checked gardens etc but she never came back 
Fast forward a year, another one was missing for 10 days. I of course did the same thing, searched and searched, turns out she had got herself wedged inside a dry stone wall! She's fine, thank god.
Anyway, as I was on my search mission for Martha (the second cat) one of my neighbours was asking me about her as I put the poster up. His wife then piped up with "didn't you lose one last year?" So I said very sadly yes, I was heartbroken. She then said "I hope you aren't as careless with your men" 
I let it go, although I was confused! Thought she must be trying to be funny. After I found the cat I bumped into this woman again, thanked her for looking out for the cat and told her what had happened...her leaving comment was "Let's hope you aren't as careless this time, try not to lose her again"
My cats are my furry babies, they are utterly spoilt and I do everything I can to ensure they are safe and healthy whilst still having an enjoyable cat life!
AIBU to be offended by her insinuation that my 'carelessness' is to blame for my poor cat that never returned?!
