Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! There is a variety of reasons that can explain alopecia or hair loss. The causes can easily be differentiated by the clinical signs associated with it and the physical exam findings. If Dinero is only showing some hair loss without scratching or overgrooming then it could conditions such as alopecia areata that can affect cats and usually resolves on its own. If there is evidence of scratching and you start noticing some redness or irritation associated with it, then other conditions such as allergies are possible. If you notice him overgrooming himself in that area then it could be something like psychogenic alopecia which is more of a behavioral issue. I think that since he is not having overt clinical signs and it is mostly hair loss, I think it is possibly transient and could resolve on its own. You can monitor this closely and if it does not resolve or it worsens then have him examined by your veterinarian. Good luck!

    I think your question is why if mani having hair loss and red spots on his stomach. The most common reason for hair loss in this region is behavioral or allergies. Some cats will behaviorally over groom when stressed or nervous. I would recommend using feliway around the house to help calm Mani. Feliway is a cat pheromone to help decrease stress. Also, I would recommend applying flea prevention every 30 days to make sure fleas/parasites are not a problem. If this does not help than it is best for Mani to go to a vet to determine if food or environmental allergies are a problem. I hope that helps
