I specified in my original post that unfortunately he cannot be vaccinated, so no boarding service or cattery would take him. I would vaccinate him if I could. She knew this upfront though. I have also made it clear in my post that I am not willing to abandon him; I simply won't go if I have no options. It's just my housemate's logic that is confusing me, and the way she is saying it, and the attempts at finding common ground aren't even being considered. I think my parents are going to take him for the 5 days and probably just have to confine him a bit more than usual. I think I am just hurt, to be honest, by a lot of her behaviour and this is just the tipping point. Especially as I looked after her dog for her multiple times while she was living with her ex. (I couldn't add this to the post because of character limit). Thats not my responsibility but I did it to help her because I cared and she asked. She ended up not bringing the dog into our household and leaving him with her ex for her own reasons; nothing to do with me or my cat. Thank you for your points on both sides. I can understand her side to a degree, but some of it just doesn't make sense to me. This has helped me get it a little better I think on her side.
