Aggressive kittys

Howdy Y'all! Sorry for not posting in a while. As you may know i have a kitten. Lately she has been very agrresive. So we took her to the vet. She happens to have some anxiety issues. We were thinking of giving her away, but decided to keep her. The vet gave her some medicine. So if your cat becomes very agressive take them to the vet. They may help.
