Thank you everyone! I guess we should feel fortunate we've gone at least 12 years on a very multi-cat household with little problems. How this got started is beyond me. It's all very depressing. Leila is at the vets today and Beavis goes tomorrow. They give them shots of antibiotics, pain meds, and anti-inflammatory meds. They help for a bit but then anywhere between 3 to 4 weeks they all need it again. The weird part is all their tests are coming back fine. We will keep it up as long as we can and then I don't know what we will have to do.
