[step] Only approach the cat if it is necessary to do so, such as a trip to the vet. The majority of agitated cats benefit from being left in peace, rather than being petted or picked up.

Ending1: Look up at the cat's ears to see if they seem relaxed. Soothe your cat by touching the ears to feel them. Ending2: [title] Ensure that your home is calm before you attempt to interact with the cat. [step] While a stressful environment can seem comforting, if there is reason for the cat to be agitated, then you will need to take steps to help it feel calm and at ease. Ending3: If you do have to approach the cat, the very first thing you need to do when your cat is upset is to protect yourself and then the cat. Scared or aroused cats can and will bite their owners and they will scratch. Ending4: [substeps] If you're watching a cat that's scared, like a cat who's not used to sharing its bed, be sure you are comfortable with your cat's environment and shouldn't approach the cat alone. It will likely feel scared and try to get away from you.
