No breeder is on record here yet. Portugal’s FIFe member club does not list this breed in its breeder directory at all, so an absence here says nothing about whether anyone breeds it in Portugal.
Medium-sized, muscular cat combining Siamese and Burmese traits. Pointed pattern with aqua eyes in mink color.
Created in the 1960s by crossing Siamese with Burmese, though the combination occurred naturally before. Combines best traits of both breeds. Comes in three pattern types: solid, mink, and pointed.
Typically 2.7-5.4 kg and 25-30 cm at the shoulder — published as one range rather than separately for males and females.
Generally described as curious, intelligent, social, lively, outgoing, playful and affectionate.
That is the breed in general, not a promise about one animal. Ask the breeder what their own line is like, and meet the parents before you decide.
Breed reference from The Cat API.
Drawn from sources rather than written as an opinion — cited health research, the registry’s own standard, and peer-reviewed longevity. The Cat API; UC Davis VGL — PRA-rdAc test. One breeder’s animals can differ from any of it, and an empty column means we hold nothing for that side rather than that there is nothing to say.
Breed-level information from The Cat API. It describes the Tonkinese in general; any individual animal can differ.
Known hereditary risks for the Tonkinese breed, and the specific documentation to request from any breeder before paying a deposit. A responsible breeder will have these readily available; deflection is a red flag.

Health checklist (PDF)A severe skull and facial malformation carried from the breed's Burmese ancestry. Kittens with two copies of the mutation are stillborn or die shortly after birth and require euthanasia; one copy causes no defect but can produce a slightly shortened face.
What to ask for
Burmese head defect (ALX1) DNA test on both parents, showing an N/N (clear) result
An inherited, untreatable form of blindness carried from the breed's Siamese ancestry. Affected kittens have normal vision at birth that degenerates from around seven months old, with most cats fully blind by three to five years.
What to ask for
PRA-rdAc (CEP290) DNA test on both parents, showing an N/N (clear) result
An inherited disorder, also carried from Burmese ancestry, causing episodes of low blood potassium and muscle weakness, most visible in the neck as a wobbly gait. It is not usually fatal and is manageable with potassium supplementation once diagnosed.
What to ask for
Burmese hypokalemia (WNK4) DNA test on both parents, showing an N/N (clear) result
This is where Tonkinese owners’ own photographs will go, from the pet profiles they keep here. Nobody has added one to a public page yet.
A photograph in a pet profile stays private to its owner. We will not put one here unless they ask us to.
No Tonkinese breeder has a record on this platform yet, so there is nothing to list. That is a gap in our coverage, not a fact about the breed.
