Hi, my kitten sumi had her 3rd milbemax tablet last July, at the age of 10 weeks. At 1.1 kg, she weighed just over the recommended weight for the adult dose. I questioned this, as she had only had the kitten tablet before, twice. The vet assured me that it was fine, but I had reservations, as I couldn't see that a 1.1 kilo kitten could safely take the same dose as a 4 kilo cat. My fears were founded unfortunately. Sumi had a terrible reaction; first she threw everything out of her tiny body from both ends, then 5 days of severe diarrhea. She was in the emergency vet, on an IV line, then my own vet again being hydrated every day. I brought her home every evening and syringed fluids and home-made chicken broth into her mouth to keep her nourished. We nearly lost her. I will never give her Milbemax again, as I think she developed a sensitivity, or allergy to it. I have been treating her with a homeopathic parasite remedy over the past month, and she is very healthy again. She is also on a raw diet, which I hope will strengthen her immune system and her resistance to parasites. A fecal sample was taken when she was so ill, and a small amount of tapeworm eggs were found. This is hard to understand, as by that time the tablet had wreaked havoc in her system. The vet said milbemax will have these side effects when there are parasites present, but how could they have survived that?
