Common questions
How much does a full-grown Thai weigh?
A Thai weighs about 11 lb (5 kg) as an adult. That is the mass Wikidata publishes for the breed under a CC0 licence, re-checked here every week.
Why is there a range instead of one weight?
Because the source publishes a range. Weight varies within any breed with sex, genetics and health, and a mixed-breed cat usually falls between its parents' breeds. Narrowing about 11 lb down to a single number would look more precise while being less true.
Does this page say what size class the Thai is?
No, and that is deliberate. Dog breeds have a widely used small/medium/large/giant convention; we found no equivalent published classification for cats. Rather than invent one, this page gives the weight and stops there.
Breeds of a similar size
Weight varies within the Thai by sex, genetics and health, and mixed-breed cats fall between their parents. This is a typical range, not a guarantee.
