question:
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.
answer:
positive


question:
Like the look of them, Thought I ordered a different pattern but that might have been my fault. They're comfortable and nice looking. Helps with the swelling in my legs.
answer:
positive


question:
The fence does not issue a warning beep when the dog approaches the perimeter -- it beeps and shocks at the same time despite correct installation and varying the transmitter settings. I tested on myself after training the dogs without the collars activated and - despite the disfunction - I am unable to reach customer service for assistance or return/warranty redemption. DO NOT ORDER
answer:

negative
