Because the genes of broken ears already carry the genes of hereditary diseases, the probability of offspring born of two broken ears suffering from hereditary diseases is as high as 80%. The onset age is generally from two months to six months, and stiff tail usually appears in childhood, and obvious symptoms usually begin to appear in adulthood.
At the beginning of the disease, because of pain, I don't like activities, and sometimes my hind legs limp; I will raise my paws from time to time, because it hurts to bear the weight, I will bow my back and walk like walking on stilts; The tail will not swing freely and flexibly, but will only be stiff; I like sitting on the ground because of the pain caused by stiff or curly hind limbs; I like to lie down big, lazy and weak, because my spine hurts.
Folded ears can no longer mate and reproduce with folded ears. As long as there are ear-folding characteristics in childhood, even cats with erect ears in adulthood can no longer reproduce with ear-folding. If ears are folded, ears are short, ears are short or ears are upright, offspring will not be 100% without genetic diseases, but this will reduce the chance of getting genetic diseases.
