Welcome Kally Cat.

How did she behave around the vomiting. If it was immediately after eating and if she was happy and hungry after- then I wouldn't worry- she may have been too greedy.

Cats vomit easily as it is a way to get rid of food that might not be good for them or to get rid of hairballs.

If she is quiet, does not eat, and if you notice that she isn't peeing or pooping then it could be a serious problem with her digestive tract then it would be better to see the vet.

From how it looked I would say it's not problematic. My Tigris does it 2 times a week
