I would like to know if Felimm can be mixed with goat milk.

It is safe to mix Felimm with goat’s milk. However, you should be careful with giving your pet goat’s milk, as it has the potential to cause some gastrointestinal upset. Pets have more difficulty processing lactose than humans do. Some pets have no trouble at all with goat's milk, but some may develop diarrhea from it. Start with a small amount, and see how your pet reacts.
