It was actually the vet nurse who recommended not rehoming her, as I did ask their advice, and I will be speaking to my vet this week. i had thought of the stress on her, as she hasn't tolerated the move here all that well, as it could make her existing kidney issues worse, but the vet nurse said that it wasn't fair on a new owner. Fortekor might not be an option as she hated 3 days worth of antibiotics. The other thing I had to think of was the fact she was already on the rehoming page (only taken off yesterday), and had been for a while with no interest, we have a number of cats in who need to be only cats, and are struggling, as the majority of people who contact us have another cat, if cats years younger than her have been waiting a lot longer, what chance do we have?
One other thing is that if I had gotten this diagnosis yesterday for Molly, I would be doing pretty much the same, the only thing I could do wiht Molly is try the food, but fluids and meds would be a no go for Molly as well. The main difference is that Molly is happy here, whereas Rosie isn't, so the decision is being made for her, if we can't rehome her, and she isn't happy here, I am not buying her time for the right reasons. She does only have one symptom at the moment, which is her saving grace.
