There is good news and slightly disturbing news, but overall good news.
The good: X-rays show the blockage is smaller and has moved a little, so it isn't an obstruction. There is also poop in the colon, which means things are being processed and are moving, they're just moving slower than they should. We have been given cisapride to help get things moving and Mickey's vet wants me to add a little mineral oil to his food to help move everything as well. I'm not keen on mineral oil as a laxative for anyone, but as long as it's a very small amount, it shouldn't cause problems.
The slightly disturbing: Mickey has lost almost an entire pound. The last time I took him to the vet before all this started was in July; he weighed a little over 6 1/2 lbs. Today, he weighed in at 5 lbs., 13 oz. You would never know it to look at him or hold him, but it still bothers me.
When we got home, I got the patient settled in his cage and went to the grocery store to get him his favorite veggies: dandelion greens and kale. The dandelion greens will definitely help get things moving, since they tend to have a laxative effect, and I can rub a little mineral oil on the kale to get it in him without using too much. We'll be back to the vet on Wednesday for follow-up; she wants to see him every 2-3 days until we know for sure he's out of danger.
As for the patient, he's currently trying to stuff as much kale inside himself as possible, after tossing one of his jingle toys around to let me know he was ready to eat. I think he's enjoying his "hospitalization" a little too much. ;)
