Quick Verdict

Use calming supplements for mild stress situations rather than severe medical or behavioral problems.

Choose the format your cat is most likely to accept: chews, soft chews or capsules.

If the stress issue is persistent, it is worth checking with a vet instead of relying on supplements alone.
