Last night (10/10) sometime between 10pm-11pm we noticed that Ives was trying to defecate without success. Obviously we became more than a little concerned and gave him some Linatone and Petromalt. Along about 3am, he started crying. We gave him some more linatone and an enema which was successful but didn't relieve his distress. Then comes the hard part - waiting for the vet to open. After an X-ray, he went into surgery for a blocked urethra. Poor little guy's urethra was full of stones from the bladder to the penis. They had him in surgery for an hour-and-a-half, back flushing him until they got most if not all of the stones. They rerouted his urethra such that he now if more like a girl than a guy ;->. He should be home any minute now and hopefully all will be well. The size of the stones was impressive. The poor little guy must have been in discomfort for some time. I wish ferrets were less stoic with their discomfort. It would be nice to get an early start on problems like these. Two questions: 1. When we were giving him an enema, how much fluid could be given? 2. Any ideas on a diet that would prevent these from forming? Because the X-ray showed little or nothing, I assume that magnesium/phosphorus are not the culprits as they should have showed up. (We will be sending some to Acupath for analysis). How common are these in ferrets? Prevention? Hugs to all fuzzies.
