Mammary tumors and Gesäugetumore and PICA are diseases where Siamese cats / Thai cats are affected above average. At this point we provide some information and sources for further studies.
PICA ( Latin for für magpie) describes a behavioural disorder: concerned adult cats compulsively suck, lick, chew or eat objects which not serve for nutrition: cotton (52%), wools (31%) plastic and rubber (36%). The cats develop this deviant behaviour over the first years of life. If you take away the preferred objects, they use other materials as a substitute.
The fretting often leads to repeated surgeries to remove the foreign objects. An organical cause for this behaviour absolutely should be excluded! If it is a behavioural disorder an approbriate therapy should be started to prevent potential surgeries and further damages.
An accumulation in Siamese cats/ Thai cats in some lines is proved and prefigures a genetical background Concernde cats should therefore not be used for breeding.
After the tumors of the lymph and blood system and the skin the mammary tumors is in the third place of the most common types of tumor with cats. Mammary tumors stand out because of the high percentage of malignant tumors concerning cats.
Up to 90% of the examined mammary tumors with cats and male cats (!) are highly malignant. Espescially in Siamese cats/ Thai cats the ration amounts to nearly 100%! There are race specific characteristics that presuppose a cumulative and early occurrence ot this type of tumor. Furthermore, a higher familianl incidence can be seen.
The appearance alone does not allow a statement to the malignancy or possible metastases. So all lumps in the area of the teats must be removed and examined.
Allegedly, uncastrated cats have a highly increased tunmor risk compared with castrated cats and hormone treatment might promote the development of mammary tumors.!
Mammary tumors are very aggressive with cats, examinations of 2016 say that the average survival rat for level I is about 30 months, level II about 14 months and level III about 10 months.
