Perfect as a personal item. NOT considered a carry on and you won't be charged for it! Wonderful when flying certain carriers that charge for everything!

Ex Output:
positive


Ex Input:
My cats are indoor, but I keep the windows and doors open, so fleas do have the ability to get in the house. One of my cats was starting to show symptoms of having fleas, and I opted to try this vs a visit to the vet to tell me he has fleas. Did some research, and gave this a try. I'm still on the first application, but flea issue has subsided. Also, not as smelly or greasy as other flea medicines.

Ex Output:
positive


Ex Input:
the piece of plastic that connects the lid to the bottle BROKE IN LESS THAN A MONTH! I didn't even use it as roughly as I have my previous Nalgene bottles :(

Ex Output:

negative
