Why is my cat chewing tail and has urine on her rear fur?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Mediumhair | Female | spayed | 5 years and 1 month old | 9 lbs

My cat has previously been chewing and attacking her tail for about a year now,&the vet has played it off as a allergy issue, she's been on the same diet since then. Recently she has gotten what seems to be possible urine stuck to her fur,but is very close to her anus,&is quite hard to wash off.i can tell it's irratating her,but she is not very kind to allow me to help rinse/wash her.her skin is red near her anus, should I be very alarmed of this.money is tight,so hoping for a home treatment...

This looks like a moderate inflammation/infection of the skin surrounding the area. It could be due to urine scald, which means that there is some other problem causing the urine to collect there. This could also be due to Ace not being able to groom herself properly. It's difficult to tell with all the fluff, but Ace appears to be a big kitty. If Ace is obese, then she will not be able to properly groom herself back there and could explain why she's going after her tail - she can't reach the spot she needs to groom, so she grooms the nearest spot she can reach. I've provided a link below to some good information about cat obesity, so you can check if this is a problem and help correct it if needed. http://www.vet.cornell.edu/fhc/Health_Information/obesity.cfm Unfortunately, this does need evaluation and treatment by a vet, because this problem can get much worse. If you can flush the area with cool water twice a day, then it will provide some relief and help prevent further damage to the skin. It's not an emergency, but it would be good to have her seen by a veterinarian at your next convenience. I hope that helps and Ace gets better soon.
