How Vinegar Helps with our Cats fleas....
Mixing a small amount of ACV in my cats water, plus a mix of water and vinegar (distilled or acv) in a spray bottle works great as a insect repellent... just remember do not get into yours or your pets eyes.
DO NOT USE TEA TREE OIL FOR CATS, we discovered all essential oils can be very fatal on the use of cats in that their kidneys can not digest it from their bodies and eventually even in small doses over time can be fatal.
So we got our 3-month supply of advantage and used it along with the vinegar (as the advantage just was not cutting it by itself) and we have noticed a vast improvement on the fleas... Of course we had to clean the whole house vacuum and steam cleaned with a vinegar solution found on this site for house cleaning... and our homemade vinegar/water spray bottle has kept the fleas off of us.
The vinegar is a great solution for our household in that we have small children plus our cats and we did not want a bunch of chemicals set loose that could be harmful to all.
Unfortunately it does take about 3 months to totally rid the house of fleas completely, as that they have a 3 month life cycle.
Thank You for having such a great site. =)
