How every kit is made
Sourced and dated
Facts come from named sources, with the date they were checked. Changes are logged, not quietly swapped.
Free to try
Every kit works for free with no account. Some offer an optional paid extra, clearly priced.
Honest limits
Guidelines, not guarantees. Where a vet, a lawyer or your state's own page knows better, we say so.
