Review: My cats are better than ever! Money VERY well spent! ❤️ - Hey y’all! I never write reviews but for this I have to! I didn’t have high hopes because it’s not a vet prescribed medication but it works AMAZINGLY! all four of my indoor babies had come down with a cold/seasonal allergies. Ophelia, the black one pictured, has feline herpes already 😢 She was a rescue from the streets. Our other three are not infected but were also hit hard by the cold. They were snotty, sneezing, lethargic, not eating, not drinking, and not bathing themselves. I ordered this on a whim because their vet allergy meds were NOT helping. First i’ll say, Ophelia eats them up like CRACK! She smelled them through the bag and started losing her mind! My other babies are more demure with it. Rad (the brown one) didn’t like them at first but it was because she was stuffy and couldn’t smell them. After the first dose, they were WORLDS better! Playing again, eating and drinking and clearly here, cleaning each other and themselves 🥰 All symptoms GONE! Even my herpes pos kitty! No eye discharge and no snot and no sneezing!!!! Make sure to know how much your kitty weighs and feed these after they eat their regular food. Follow the instructions and do not just plop down a handful on an empty stomach. I suspect a lot of the bad reviews are from people improperly giving this medicine. Our cats have never been better! I highly highly recommend! They don’t have a strong smell at all. The package is small, but plenty of treats come in a bag. Ophelia and Rad weigh 7 pounds each so they both get 7 treats. Baby, the white color point, gets five because she weighs 5 pounds. If your cat refuses to eat them, dose these like a pill. Insert through the side of their mouth to the back of their throat then rub their throat downwards to encourage them to swallow. After they can breathe again, they are more likely to eat them naturally. I love my cats like they are my children ❤️ And these are a great choice!
Review: ⭐️⭐️⭐️⭐️⭐️ Great immune support for my senior cat! - I started giving Pet Honesty Cat Immune Support Lysine to my 18-year-old cat because she occasionally picks up colds that really affect her energy. I’ve been trying to boost her immune system, and this supplement truly seems to help. Since starting it, she’s had fewer sneezing episodes and overall seems more comfortable. She actually likes the flavor, which is a huge plus—I just give it along with her treats and she takes it without any fuss. Knowing it includes lysine, colostrum, and omega-3s gives me extra confidence that she’s getting real support. So far, I’m very happy with the results and will definitely keep using it for her.
