I have been adding vinegar to Naranj's and P. K.'s water for about six months. I use a glass loaf dish (so P. K. can't turn it over) and add an 1/8 tsp. of vinegar to fresh water each day. I take both cats out every afternoon for a walk and I have yet to see a flea in the apartment.
I tried this with Apple Cider Vinegar - Keegan (GR) drank it no problem.
When one of my cats was at the vet - who also "talks" with animals - I mentioned me doing this and that Kylie wouldn't drink it she said "well yea - she is saying she isn't going to drink that S#!T!
