Why is my cat lethargic, losing weight, and has a red spot on her leg?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Mediumhair | Female

I have a cat, her name is baby. She was very healthy and active and sounded very well and strong. Now all of sudden she's not active as much as she used to be and her legs are getting thinner and there's a red colour patch in her leg all of sudden. I keep her in a room and i gave her proper cat food, the problem is I couldn't spend time with her as i got college and she's in room all alone for a whole day. I don't know what to do now.

I'm not sure how old your kitty is or if she is spayed or not; however, if she is acting more lethargic than normal and losing weight, then she may have thyroid disease. It is best to get her checked by your veterinarian and tested. The red spot on her fur is hard to pinpoint the cause of this. It appears to only be the haircoat, so let the vet take a closer look at this and the skin to determine what this could be. Most cats are very independent, and only require little affection from people, so don't feel too bad about not being around all the time. Just make good use of the time that you do have and show her that you love her. I hope that Baby is going to be ok moving forward. Best of luck and take care. ; )
