PeekAPaw stocks nine Protexin Veterinary supplements for dogs, cats and rabbits: probiotic pastes, powders and capsules for the gut, two urinary support options, a vitamin B12 capsule, a leave-on skin mousse and a calming sachet.
Three of those choices are easy to get wrong. Fibreplex is a rabbit product — a carrot-flavoured, high-fibre paste to support normal gut motility — sitting in a range that is otherwise dog and cat, so check the species before you order it. On urinary support, Cystophan is made specifically for cats and pairs the bladder-lining ingredients with L-tryptophan; CystoPro is the dog and cat one, using cranberry powder and a gut probiotic instead. And the two Pro-Kolins are not interchangeable: Pro-Kolin+ is a paste given up to three times daily depending on severity, while Pro-Kolin Enterogenic is the powder Protexin designs for long-term daily feeding, and its instructions say simultaneous use alongside oral macrolides should be avoided. SereniCare needs forward planning rather than a species check — Protexin's guidance is to start it two weeks before an expected anxious event, and it may take up to six weeks to show an effect in some animals, so it is not a buy-on-the-night option for fireworks. Where a problem is ongoing, talk to your vet: these supplements support a treatment plan rather than replace one.
