I hope you manage to get something sorted out for them. I spent a couple of years trying to persuade a woman to get her cats done, they were breeding and breeding and breeding
I even got told to leave her property at one stage
I didn't give up though and went back pretending I wanted a kitten or two for my youngster
Silly mare didn't even recognise me and after buying the two remaining kittens off her, I then got onto the subject of her then pregnant cat that was due to drop any day
I told her my friend was after a tabby in the hope she would part with her whilst pregnant but sadly she wouldn't
Anyway cut a long story short, I put my name down for all her kittens and told her I had a few mates that would be interested and I would take them all
After a couple more visits and gentle pressure, I then even managed to talk her into having her females done as she'd mentioned she was sick of all the tom cats hanging round
When I returned the females to her, I then got the males done and thankfully her garden has since remained kitten free and the cats are much happier
