My cat is 13 years old. This past summer, we brought a new cat into the house. SInce then, my old kitty has started losing hair, losing weight (although I am not sure if she just looks skinnier because she is losing hair), grooming excessively, and recently, I noticed small black spots on her pink tongue ( she is an all black cat). She has always been a urinator, meaning when she gets fussy about the litter box, she pees elsewhere. But I feel as though she is having other problems. I must admit, I fear taking her to the vet because I have 2 other cats and I am afraid of a diagnosis that would effect my other babies. I have also avoided the vet because my old kitty's personality has not changed a bit. She is still very active and extremely affectionate. She avoids the newest member of our household, the kitten, but she does not seem sick. Additionally, a good friend of mine in Houston takes her cats to a homeopathic vet who claims that indoor cats can contract illnesses from the vaccinations required by most vets. My cats never venture outdoors, not by choice, but because I don't let them. I worry that giving them the shots required for cats will make them sick for no reason. Please help me; my granny cat has stood by my side for 13 years and has been a blessing through it all. I worry that she is sick but she seems fine, mentally speaking, and I am a bit in denial about feline illnesses. Thank you, Erin
