I'm sorry to hear that both of your furkids are throwing up. I know that mine will throw up from time to time and Cirrus threw his dinner up just last night. It's so hard not to worry about them but I try not to panic too much as long as they're still acting normally.
I sure hope that Mishi feels better soon and that it's nothing serious. Prayers and positive thoughts are still being sent your way. Please take care and try to update us when you can.
