14wo rescue kittens. One is absolutely fine but one is crapping syrup! He had it a couple of days after arriving two weeks ago and I assumed it was the changes etc, it sorted itself out within a day but he's had it again and today is day 2.
Any ideas on food etc or anything I can give to help? They are currently on Felix kitten wet food with whiskas kitten biscuits, which is what they had at their foster home. I make sure he has plenty of fresh water. He is fine in himself and has had no vomiting or anything else.
