The hair on the belly which is missing can be a normal finding in a small number of cats, but the hair loss on the side of the body seen in the picture is never normal. Typically the first thing a vet will want to know with any situation involving hair loss is if it is occurring with or without itchiness. If there has been itchiness, the cause of the ailment is most likely allergic, inflammatory, parasitic, infectious, or auto immune in nature. If there is not an itchy component, the cause may be hormonal, psychologist, or also potentially, inflammatory in nature. If Pipi appears to be uncomfortable or is mutilating herself in any way, I would encourage you to have her examined at the next available appointment time. Provided she is still comfortable and not hurting herself, simply continue to monitor for any changes or worsening condition, and make a regular appointment to be seen at the next convenient time. Hope this helps.

    Poor Sadie! I'm sorry that she's having this problem. Hair loss in particular areas like this can be caused by a number of different issues. Some common possibilities would include allergies, fleas, a bacterial or fungal skin infection, or skin mites (mange). The knots on her stomach could be mammary tumors, some other type of skin growth or tumor, or even a severe skin infection.

    Sadie will need an exam and some diagnostic testing by your vet in order to determine what is causing these issues, so I would recommend taking her in for a visit as soon as you are able to. Your vet can do some simple skin tests to help diagnose the reason for the hair loss, and may also recommend a biopsy or other testing of the knots on her stomach if needed to determine what they are.
