DM's neighbour has a swimming pool, which is actually a huge hole in the ground containing 2ft of stinking stagnant water. Over the last few years 5 cats have drowned in the pool, 3 of which were owned by DM and 2 by other neighbours. Also a fox, countless rodents and hedgehogs have met their end in the death pool.
After the first of DM's cats drowned the neighbour seemed genuinely upset and agreed to cover the pool. It didn't happen and a while later DM lost another cat. There was another discussion about covering it or at least putting something in it that trapped animals could climb on to, again it didn't happen and recently cat number 3 drowned too.
DM was devastated by the loss of each cat. I suspect emotions were running high and she was not particularly polite when discussing the latest one with neighbour. Neighbour is angry that DM went onto her property to look for the cat when she was out and has now said she is not going to do anything about covering the pool and DM should keep her pets off her land.
DM is very upset and anxious about her cats. She keeps them in all night and worries herself sick whenever they put a paw outside in the day. They can't really be indoor cats, DM has a small holding and they are outdoorsy country cats.
Given that you can't control where a cat goes, shouldn't the neighbour agree to at least chuck a bit of wood into their pool?
