I have 4 pet rabbits and boy do they love to chew on strings! I had to replace chargers at least once a month (sometimes more often) until I found a cable for the LHJRY micro USB charger. I had it for a few months and not only did it save me money, it made things worse. Rabbits are very curious by nature so when I first brought them home they tried to chew on them but now they don't even bother. If you love your pets as much as I do and it's impossible to keep them off the string, give this product a try. I love it and hope you do too!
