The Vet's office here is suggesting the edible Nexguard. That's what we're using on the dogs. The cats don't get outside any more.
I won't use any OTC product on the animals. I cheaped out one time I was short of money and bought an OTC topical and lost one of my Persian's within 2 days, and almost lost the other. She staggered for almost a month and couldn't jump, but finally came out of it.
