help my parents cat that they have had for 11 years has a lump on the side of her belly,it started off small but then got real big,and its open and smells real bad all she wants to do is lick it but my parents are worried about her getting sick or hurting it so they clean it with peroxide everyday and put a bandage on it so she dont lick it..this is really hard on my parents my father just lost his job so they barely have money to take care of them selfs..they really dont know what to do.kitty(her name)is not eating or drinking as much she also hasnt been using the litter box much also. she is old so she dont play much anymore and shes fat
