This is your common household cat flea.
While bathing your pet, if you see what appears to be a flea, immediate treatment is necessary. Fleas reproduce and spread at a very rapid pace. Complete infestation happens before you know it.
A common way to test to see what your flea population is, take a piece of white paper, lay it in the middle of the floor and walk around it in a normal manner. The fleas will migrate to the paper and you can then judge the severity of the infestation.
Fleas or no? Yes, you have fleas!
This is also Flea. But we do not treat these kind! We can only do what we can do! You have to laugh sometimes! That is his name!
