Works good for checking for fleas on my outdoor kitty.

Pros: worked good

Cons: none

This is a good product to use to supplement regular flea treatments for outdoor animals. For example, you might use this in January, to see if our warmer temps make it necessary to continue treatments through the winter (can you tell I was caught offguard last year?).
It could lessen the number of chemical treatments needed, but could give a false sense of security.

Pros: safe

Cons: visual inspection shouldn't replace regular flea treatments

I used this on my cat after I adopted her from the shelter. It works great. It is not irritating and pulls the fleas from the fur.

Pros: Works great

Cons: none

Use flea combs to detect the presence of fleas or flea droppings (pepper-like, blackish material that turns reddish if wet on a white piece of paper). Use Advantage or Frontline to treat or prevent fleas.

Pros: Great for detection of fleas/flea droppings

Cons: Not appropriate for treatment of fleas

I bought one of these little combs some time ago in the grocery store. It worked fine to pick up flea dirt out of my short hairs as the teeth were tight. They didn't seem to mind me using it either. However, the teeth broke pretty quickly. Won't buy another.

Pros: inexpensive

Cons: Teeth break with much use
