Sorry to hear you have a sick cat! I can’t offer medical or behavioral advice without meeting the animal. We strongly recommend seeking medical advice from a veterinarian.
Once you’ve done that, remember that their diagnosis is not the final word. Alternative treatments like diet changes, and acupuncture can help. Just as if you were diagnosed with an issue, head to the internet and research away! Check-out online pet forums/groups, chances are, many guardians have already experienced the same thing you are, and shared what treatments worked for their cat. Watch the video below to learn more and see how researched worked for me.
