You should not be giving your cat ANYTHING without discussing it with your vet. None of us are doctors here and cannot or should not give medical advice. Folks can direct you as to questions you should ask your vet about medications they have used successfully, but that isn't advocating that you use those medications.
Please talk to your vet or a holistic vet about this issue.
