@duglop Keep an eye on your kitty.
If she throws up with more and more frequence take her in. My cat was diagnosed with a serious illness after throwing up repeatedly. Taking her to the vet savid her life.
@Jacki cats hide their injuries or illness but I can tell with her because how she acts... she's a very active cat always playing so when she lays down like she's doing and doesn't do anything then it's most likely an upset tummy
