Omega-3 Improves Your Pet Health

I sometimes work in the crawl spaces under houses where ferrel cats live, This means lots of jumping biting black pepper -better known as sand fleas(cat fleas)! A lot of the other guys that do my same job wear a cat flea collars around each ankle. Can this lead to any health problems if worn for extended lengths of time? I know some of the solders in Iraq and Afghanistan do the same thing.
