If I have to fast one of my cats, I always right it down on my calendar so I'll remember. Before Sunny had his teeth cleaned, my vets office did call and leave me a message to remind me to fast him. I think that the vets should try to call their clients more often to remind them of things like this. Mary, I'm sorry that Callie had to stay at the vets for 2 hours without anything being done. Good luck on Monday.
