We understand if this may be confusing for some of the visitors on our website!
The reasoning behind this is primarily linked to internal and external search functions. For example, if you are solely a dog (or cat) owner, and you are looking for a supplement for the type of pet you have, you would not be seeking a product 'for cats and dogs' - you would be seeking an item for the type of pet that you have. In essence, it boils down to keywords; we simply want to make it easier for our customers, or potential buyers, to find what they are looking for.
The majority of our supplements are interchangeable, with the exception of a couple of products.
If you happen to notice that the band on the lower portion of your bottle is blue instead of green, or vice versa, this is also linked to the above. We use this for inventory and marketing purposes, but it does not indicate a difference in the supplement itself.
