I adopted my kitten Mario when she was just a week old. Her mom “threw her away,” and I couldn’t just watch her die. I went to the local Tractor supply and got the PetAg milk. She was fine. When we ran out of milk, luck would have it they were out of PetAg. I went to WalMart and got the liquid Hartz milk replacer. Mario was still fine. The day before yesterday, they were out of the liquid so my husband bought the powdered. It’s 7:45 now and we’re waiting for the vet to open. My almost 6 week old Mario has been throwing up and having diarrhea ALL night. Now she won’t open her mouth to eat when her usual self tries to take off your fingers to get her bottle. I have gotten so attached to Mario and have been crying since we’ve been up. She doesn’t want to eat any and won’t try to walk. DO NOT FEED YOUR KITTENS THE POWDERED KITTEN MILK REPLACER. She was fine until we fed this to her. I just hope they can help Mario.
