Microwave the water then mix in the critical care..
But it doesnt need to be hot....
Microwaving it with the cc mixed runs the risk of too many hot spots and potential for burning the cc.
Good to know. I had stuck his bowl in the fridge since he didn't eat much of it. I will just throw it out. I ended up syringe feeding him anyway. Thanks for the response.
If its from yesterday you can add some hot water too it because its likely thickened over night. Then you can always run the syringe filled with CC under hot tap water/in a bowl of hot water for a bit.
