If both beta globin genes code for the sickle protein, the person has sickle cell disease. Sickle cell disease is determined at conception, when a person acquires his/her genes from the parents. Sickle cell disease cannot be caught, acquired, or otherwise transmitted.
For every year of the cat's life after age 2, one cat year equals approximately 4 human years. This is based on how cats mature - for example at around 10 - 11 human years most cats start to slow down quite a lot... This is when they're getting to about 60 years old in Kitty terms.
This means if your cat is six years old, their equivalent cat age in human years will be around 41. According to some sources, the worldâs oldest cat lived to be 34 â thatâs 153 in cat years! Some breeds will live longer than others â for example, on average Siamese and Manx breeds are said to live the longest, so could reach a ripe age in human years!
