My almost 3.5-month-old kitten, Jasmine, has been having soft, smelly stools (semi solid, not runny) for the past two days. She's eating and playing normally and isn't lethargic. She's been dewormed regularly, with the last one on November 19th. Vaccination is up to date. A friend suggested giving her Enterogermina. Should I give it to her, or is there something else I should do?
