Vibes for {{{Marlee}}} ! It’s good to read she is somewhat active. That will help.
If it’s not full obstruction, maybe oral re-hydration salts could help. They do contain glucose. That’s a ready form of energy for her if she’s not eating. So not a bad thing but do talk to vet first. Many of human re-hydration products have aspartame in them, so ideally, get something through the vet. You could even ask if making your own with just salts would be worthwhile. Salt will help water stay in the body longer. Rabbits often go for the saltiness too. Gooseman has been lapping at the paper towel I’ve used to mop up saline lately. There’s a thought… Maybe check with vet if okay to give bit of the SubQ saline orally??
If the impaction hasn’t softened and moved, she might need to get fluids intravenously. If you do go to gut motility drugs, Ranitidine might be the go. I only know it as Zantac, not sure on its other names, sorry!
