If you have the unfortunate experience of a sick Latte, remain calm.
The sign that she will throw up is very obvious: she will start smacking her lips as if she were trying to swallow. It will get more intense, and she will usually start to stand up. At that point, we strongly suggest picking her up and moving to a hard floor, or outside if you can.
In most cases, she is actually very good about telling you that she is going to puke, and knows that she can go outside to throw up. She'll move quickly if you do.
We give her half a pill of generic Pepto crushed up with her food. She knows it helps her and will usually eat it right up. If she doesn't eat right away, leave the food out and she'll eat when she's ready.
Her belly will start making odd noises that indicates she needs to poop. It sounds like her stomach is growling from hunger. If you take her out and she poops, great. Give her about half the purple cup of food with crushed up Pepto on top. If she doesn't eat it, no problem. She'll come back when she's ready.
