Frodo arrived in our care at three days of age. Found abandoned under a deck, the home owners waited to see if mom would return. When she did not, they removed the kittens to a safe place and reached out for help. Frodo needed feeding every two hours around the clock. The necessary switch to formula was likely the cause of her gastro upset, resulting in severe diarrhea. We gave her sub Q fluids to address the dehydration and administered probiotics to help settle her tummy. It took several weeks for these gastro issues to resolve.
