The reason I bought this is because I have a male cat who gets urinary blockage, and sees his vet almost monthly on an emergent basis, and has three other vet prescribed medications for the issue. I bought the tinkle tonic as a supplement to promote easier urination, but not as a replacement for any of his prescribed medication, and these decisions should always be discussed with your pet’s veterinarian.Let’s get the cons out of the way first. The taste is terrible apparently. My cat who loves treats, dry food, wet food, and tries to eat sticks, rubber bands, pennies, plastic and any other thing you try to hide from him, audibly GAGS when I give this to him. He’s been on it about a week, 2x/day , and yesterday was the first day I noticed he didn’t gag from it. The taste must be pretty bad. Since he gets it twice a day, I always hold it in front of him for a moment before I give it to him so he can smell it and kind of brace himself for the taste.On the flip side, using this twice a day for my cat, by day 4, I noticed the volume and frequency of his urination has easily doubled. He’s also awake more often and playing a lot more, too. He also licks his nether region much less frequently. He hasn’t been on it long enough to know if this truly reduces the number of emergency vet visits for him, but I’m hopeful.My cat is a large 15 pound male cat. I started him at the lowest stated dosage, which is .25ml. After a few days I was concerned that the smallest dose on the bottle was still a little too much since my cat’s body already processes three other medications daily (even though my cat was in VERY good spirits and highly energetic, it’s good to be cautious). So I stopped giving the tinkle tonic for 24 hours, and then giving it to him again I use .2ml instead, and he’s still on track. From my experience, it’s better to start with a lower dose and slowly increase to test tolerance but I forgot to do this at first. The bottle states dosage for cats and dogs, but no mention of weight so be aware of the dose and even talk to your vet if you have questions.All in all, I’m very glad I was able to find this tonic. It seems to make urination flow more smoothly for him. Very happy with the purchase and I’m already planning on ordering some more to stay stocked.
