Relatedness testing is strongest when the comparison is specific
Testing two cats because you suspect they are littermates is a different scenario from testing one cat in the hope of identifying an entire family tree. Consumer testing works best when the comparison question is clear from the start.
The cleaner the question, the easier it is to interpret the result once it arrives.
Good sample handling matters even more with two cats
Relatedness orders depend on multiple samples being clearly separated and correctly labelled. A mistake that might only delay a single-cat order can make a comparison much harder to trust.
That is why multi-cat households should prepare collection materials before either cat is swabbed.
- Label each sample before collection begins.
- Record which cat matches which kit immediately.
- Keep the comparison question in mind when reading the result.
Relatedness does not explain everything about two cats
Even if two cats are closely related, behaviour and social dynamics can still differ dramatically. Use the result as family context rather than a full explanation of personality. The multi-cat household page goes deeper on how owners use this information in day-to-day life.
