Highlighted Reviews
"Comfortis always does the trick to get rid of the fleas on two Yorkies and seems to do well with their sensitive stomachs. My girl does not like the taste and I have to force her to take the pill but Comfortis works very well!"
"This product has NOT worked! $125 and fleas are still everywhere on both my cats! It's so bad I had to spend almost $100 to take Chance to the vet because he wouldn't come out from under the bed. I have had to spend $296 including the Comfortis on killing fleas!"
Bottom Line
Comfortis Chewable Tablets are a decent option for flea control, but potential buyers should be aware of the high cost and possible side effects, especially in sensitive pets.
