Lightbulb LED Bulbs harm pets??

I'm dumping all of my CREE because there is anecdotal evidence that LED bulbs cause harm to bunnies and chickens. It suggests that LED light bulbs may have an adverse effect on the life of small animals. A recent post by René van Gemert, CEO at Salescraft, S.L., on the LinkedIn discussion group “Innovations in Light” recounts the tale of a customer who started using LED bulbs at his rabbit farm.

I just want to confirm that if the fact is true, will it affect human as well?

Thanks.
