One dog, one cat, one shelf of supplements — and one very reasonable question: can they share? Sometimes yes, sometimes no, and the "no" cases are the ones worth knowing cold.
When sharing works
Plenty of veterinary products are explicitly labelled for both species: Zylkene, Proviable, 4CYTE, Proflex UC+, Denamarin (in the appropriate strength), and many omega-3s. The label is your permission slip — and even then, doses differ: a product shared between a 30-kg dog and a 4-kg cat is two different regimens from the same jar. Follow the species-and-weight chart, not habit.
Where the danger lives
Cats are not small dogs — their livers process things differently. Essential oils, high-dose alpha-lipoic acid, some dog-formulated skin products, and permethrin-based dog flea treatments (the classic, sometimes fatal error) range from risky to lethal in cats. Flavourings and carriers in dog products can also be inappropriate for felines. Rule of thumb: dog-labelled products never go on or in a cat without a professional saying so; the reverse is safer but still worth checking.
The multi-pet shortcut
Bring us the household roster — species, weights, medications — and we'll tell you which jars can be shared, which need separate versions, and which single dual-species product could replace two. It usually saves money and cupboard space, done once, properly.
