Your mother loves cats. He has two, but time from time he feeds stray. Perhaps they infected these two cats with something. You do not know what may be the reason. You told my mother that she should not feed alien cats, but she loves them and she does not feel like listening to you. What to do, in the end, animals are human's best friends. However, you must act before the cat becomes something bad. Call Abivet Veterinary Clinic and make an appointment. It is worth doing something good for our pets sometimes.
