I lost my MIL a few weeks ago, 15 months to the day after DH died. She was just a few weeks short of 90 and had a full and interesting life. I loved her very much.
MIL had a cat, now about 10+ years, whom she adored. The cat has been an indoor cat, although had access to a balcony/patio area (London) and was the only pet. He was originally meant to be for my niece, which was fine when she was a child, but she is now an adult, away at university, so cannot take the cat.
I said to my DD that I would not want the cat to end up in a cat's home, and that we should take him rather than that happen, although it wouldn't be ideal to have him. We already have a cat, who is an outdoor cat, and a dog, who is fine with the cat he has always known, but I worry how he would take to another cat, and also how the existing cat would react.
Anyway, following my conversation with DD, who adores animals and who loves MIL's cat, she told SIL that we would take the cat. SIL said she was very relieved, as the cat has been a source of worry, and she is fearful of taking him herself, as her flat is on the 12th floor and she is afraid that the cat may get over the balcony.
So I feel that I have been put into a position where I should take MIL's cat, and I also feel that this is the last thing which I can do for her. I told SIL that I would take the cat for a trial period, to see how it works out. I also told her of my concerns, especially as he would need to transition to being an outdoor cat, and that I was really worried that something could happen to him 'on my watch', as there is a busy road nearby. SIL said she understood the risks, but still seemed keen for us to have him.
However, the more I think about it, the more concerned I am. I don't want to let SIL - or MIL - down over this, but I am anxious that it won't work out and that something might happen to the cat, or that he will have the stress of being re-homed twice. So I am thinking of saying to SIL that I have thought it over more and have changed my mind, but don't want to add to her burden when she is grieving for her mother so much and has many other things which she needs to deal with. I really don't know what to do. Would I be unreasonable to say that I have changed my mind?
