I hope that Phoebe's spay goes well. I'm sorry to hear that Apollo and Hercules are sick. I would think that your vet would at least be able to squeeze them in since they are sick. This is what my vet tries to do for me. I hope that they'll be able to be seen by a vet soon and they they'll both recover quickly from their illness. Lots of prayers and positive thoughts are being sent their way.
