Makes me wonder if the poorly one that died did have a temp, but instead was below normal readings, and was already on her way out of this life?
I know how you feel Angie, so will a lot of people on here too, you feel trapped, helpless and stressed by it all.
These poor cats didn't ask to be born, which is why the spay and neuter message is so important, also vaccinations. I think there seems to be a lot of nasty viruses out there at the moment, I don't know the cause, but it could well be due to overbreeding cats which are far too plentiful at the moment, and people take them on with less thought than choosing a box of chocolates. Five minutes later they are bored of them.
Take care, see you later when I come to collect the crush carrier.
