I experimented with the syringe by drawing out and replacing without removing the syringe. The syringe does not eject all of the medicine. What is in the tip stays there. The syringe is well made.

So I squirted what I hope was the correct amount on her food. She ate most but not all of it, so I threw the rest away so that the others don't get it. I might try squirting in her mouth tomorrow.

I have to give it twice per day, morning and evening. I'm just wondering does it have the be the exact time every day or do I have a 1/2 hour leeway?

I may make a trip to the vet tomorrow just to be sure.
