People do love their pets．Some people bring dogs into their families while others prefer cats．And then there are the people who love their spiders．Many spider-lovers like tarantulas(狼蛛), big, hairy creatures that don't have venom(毒液)．And because tarantulas are usually calm, some people even buy them for their children．
If you're considering taking home a tarantula, however, just think about the recent case of a 29-year-old tarantula owner in England．It may show why these spiders makes terrible pets．He had conjunctivitis(结膜炎)in his right eye．
His doctors were puzzled because the swelling wasn't responding to medicine．In a recent study, the doctors reported seeing“fine hair-like projections(投影)”sticking out of the man's eye．When told about his hairy eye, the man knew exactly what the fine hair-like projections were：tarantula hairs．
In this study, the tarantula owner told his doctors about something that happened as he cleaned the spider's home．He was trying to remove a stain when he saw the tarantula move．He turned to look at the spider, and the spider released a mist of hairs which hit his eyes and face．The doctors couldn't remove the hairs, so they prescribe(开药)eye drops containing a strong medicine．After eight months, the man's eye still wasn't completely healed．
In 1997, a report described three patients with“itchy, red eyes”．Guess what?These three people had crossed paths with annoyed tarantulas too．One of the patient's eyes didn't heal for three years．The other two were still experiencing pain in their eyeballs 2 to 6 years later．In 2003, a report told the story of a 14-year-old boy who had also received an eyeful of tarantula hairs and bee bitten．
There's no explaining why people love particular kinds of animals．But people who decide to keep tarantulas should be prepared to handle their beloved pets with goggles and gloves．
