Cat tonic

Please make this product more readily available. I visited 7 stores/pet shops today and eventually found at Petworld Brackenfell.

My 18 month old cat has been struggling with a chronic cold, she's had two rounds of antibiotics over the past two months which is not ideal.

I started using this tonic when she was only 7 weeks old and very sick, so I know it works. But it is hardly ever in stock so I have stopped using it for a long while.
