Hello! It looks like Tiger’s growth on her abdomen has become infected. The other growth could be related, or it could be a different type. I would recommend having your vet check Tiger and take a sample of the growths to determine if they are aggressive and need to be removed. Based on your photo it does look like the growth is causing discomfort and removal may be recommended regardless of what it is. Best wishes to you and Tiger!
