Enisyl - F is must in every breeders cupboard. I am a breeder of Maine coon cats and I give Enisyl-F paste to boost cat immunity system. And my vet recommended to use is after kitten vaccination. All my adult cats loves it, so it should taste very good. They just comes and licks. Kittens don't like it so much, but it's really easy to pump one pump straight in they mouth. It's 100 ml bottle, it's lasts for long and it's great value. Easy dosage, just press a top of the bottle and place gel straight to the mouth or mix it would food. Highly recommend.
