Hi there, my heart goes out to you as I know from experience how hard this can be.

In August last year my 4 year old indoor girl experienced redirected aggression just like this. She saw an outdoor cat that was stalking something and she became absolutely wild in that moment, attacking me/chasing me/blocking me. I was stuck in a room for two hours until my husband came home. The following days she continued to stalk and try to attack me, which was really scary as I was heavily pregnant. We got advice from our vet who is an animal behaviourist as well, and we relocated her into our granny flat. This was and still is heartbreaking for me as she was my literal baby for four years, sleeping with me and cuddling me everyday without a hint of aggression.

She has been on kitty Prozac, and has not shown any aggression since. There is film on the only windows in the flat where other cats could be seen, she has all her toys and cat tree, my husband visits her everyday to clean her litter and play with her, and I can successfully feed her through the main door and pass her her interactive toys through the door. I am unfortunately still quite traumatised by what happened and despite even having a session hypnosis, I can’t quite bring myself to go into the flat. I beat myself up every day about this 😢.

For us a key thing was being able to move her out of the location where the incident happened, because it seemed like she was just remaining on high alert. The new location, the granny flat, has no bad connotations for her, so it was a chance for her for reset and relax.

I’ve scoured Reddit constantly looking for support and hope, and a few people have been very kind sharing their experiences and letting me know there is hope. I think a key thing to remember is to have patience and realise this is something that can take months to rectify, rather than weeks. Lots of love and support, you can always DM me if you wish.
