Mental neighbours trying to take our cat!

[interestinglino]

My slightly weird and mental next door neighbours took one of my cats a few years ago - the cat in question didn't like it when I got a puppy, but I'm sure it would have come round to the idea, except they started taking it into their quiet, dog-free house and feeding it. By the time I found out what was happening, the cat would have nothing more to do with me .
I now have another cat, who is coming up to a year old now, in a conversation with the neighbour, I have asked her to make sure she doesn't let it into her house, but when I call the cat, quite often it won't appear, then they open their door, and the cat then comes, so it's obviously being taken into their house.
Part of me really wants to keep the cat indoors full time, but it was from a farm, and really loves being out and about.
I really don't want to fall out with my neighbour, but I think she is being very unreasonable by taking the cat in.
Any tips on how to deal with this?

Tell her your cat suffers from a digestive disorder and needs specialist food, very expensive specialist food. And medication.

So under no circumstances is she to feed the cat. My cat has a sensitive tummy, no one wants to steal him as friendly as he is because when they feed him wet food, he inevitably dirroreahs all over the sofa . Unfortunately, he then comes home and does it in my house. I now have on his collar "I have food allergies, please don't feed me". You could try somehing like that.

I'd also make sure that the cat is microchipped, so there can be no doubt as to ownership, but I really hope it doesn't come to that

ditto microchip. They will then be unable to get the cat microchipped in their name. It does happen!

Make sure you feed him really good food. Perhaps even over-feed him (although that's bl**dy difficult with a cat!). Then he won't actually want to go next door - unless they have a housefull of catnip or something.

There are some strange people around, let's hope THEY havent got your cat mircochipped.Why dont they re-home a cat, if they want one that much, i dont understand people like that.

Can you tell a white lie and say that the cat is diabetic so can only have the special and expensive food from a vet? If your cat stops getting food there, but still gets fed at your place, he/she will soon remember where home is.

My cat is a greedy guts that would go anywhere he's fed and is a bit of a wanderer so I got him a name tag for his collar saying "do not feed-diabetic". Since then he's stopped his 2 days jaunts as when he gets hungry, he has to come home.

get him chipped deffo and tell neighbour he has pussy cat ibs an attack can come at any given time

Yes, defo make up a digestive disorder and then say that if they don't stop feeding the cat you will expect them to contribute towards the vet bill.
