MY cat is losing chuncks of hair,when you pet her she has what apears to be sores. WE bathed in flea soap and put on new coller.however the problem still there .The cat is a in door cat. she dosn't seem to have fleas.
Your pet may have a allergy and/or a milliary dermatitis. I recommend that your vet examine your pet. Your pet may need a shot to help the skin condition. Thanks, vetcare
