​Most cat owners believe that if certain antibiotics like penicillin are safe for us can also be safe for cats. This is completely correct. In today’s time, going to the vet can be very expensive so many cat owners do the treatment by themselves by looking for ways to alleviate the condition of their cat in a way that they use the drugs that are available at home thus, making it useful for cats as well.
