I have a bag of sterile saline from my vet. I heat it up to body temperature in my microwave. Then I fill up my syringe.
I flick the syringe a lot to get the bubbles out and then I squeeze the plunger to get them out.
Mooshy is hard to inject because he's so thin and dehydrated.
When I'm done, it looks like he has shoulder pads. Slowly his body absorbs the saline and rehydrates him.
See how sunk in his eyes are? That's how I know he's dehydrated. Poor guy. It's going to be awhile before he gets all better and stable.
