2 of our 3 cats have regularly output, which leads of course, from being introduced from time to unwanted guests home with them.
Intolerances we could see in any of the 3.
Sorry, we have one of our cat flea faeces found in fur and after two gift (waiting time with TA discussed) of Advantage.
And completely free of ticks he did not remain unfortunately.
Although the attack was not as bad as not entirely disappeared before the treatments, but it is still by far.
With our two other cats but we had no infestation.
Here we have an animal keeper that their pets for fleas neither nor other with us in the neighborhood.
So I suspect that my cat there regularly "new fleas" At length, and these do not die immediately,
What then explains the flea dirt.
In addition, I recommend everyone with fleas all textiles etc. etc to wash whenever possible and sprayed with a spray environment for fleas
The only way to fight the fleas in the long term.
But all in all, the product has a good price-performance ratio.
