Hi,
I think I would error on the side of caution. My first experineces with EC was with Sabrina and Yoda. At the time, nothingat allwas known about things like this...unfortuntately, some vets still don't know about it. The early indications were a little stumble every now and then, a miss hopping into or out of the litter box or falling off a ramp in their multi level condos they were living in. We lost Sabrina and we really didn't know why. Yoda started by dragging a rear leg ever so slightly. Then it would look like on of his rear legs would "give out" as he hopped up his ramps causing him to fall over. Then he got all better.We thought it might have been due tothe configuration of hisramps...so I modified them so we thought that was the end of that. In a few days, he started doing it again...only more pronounced. We came in one afternoon and were getting our buns ready for the trip to our beach house when we noticed that Yoda wasn't acting right. We let him out on the floor and he fell over into a spin. He was in a panic and so were we. We rushed him to our vet and discovered he had an ear infection. We treated and he got better. Again, in a week or so, he started presenting the stumbling again and starting having urinary problems. Another infection. Treated and better. In another week or so, he started showing the leg problem again...but this time, he was on his side and couldn't get up. This "yo-yo" effect went on for quite a while. The problem was E Cuniculi. It was causing his stumbling due to the neurological issues it causes. The infections and continuing neurological issues were due to his immune system mounting an ever increasing counter attack. It is a "wasting" disease in which you can actually see the life being pulled out of them.
I hope this is a case where I am way off base and totally wrong. But we have seen EC so much now that we easily recognize the early signs...and we are able to start treatment earlier. If it is EC, it is quite difficult to successfully treat but there are some good possibilities being researched by some of the top researh vets. Again, hope I am wrong...but I would error on the side of caution.
