Coco is still licking and has started coughing again she also has a whistling in her nose. She is eating well hasn't lost weight and is her normal self. I know the licking has become a habit which she enjoys, she doesn't have fleas and has nice skin. I give her furball paste and she also likes to lick twice a day petroleum jelly. I was going to book an appointment with the vets for her on Saturday but it makes her stressed out. When she wakes up from a nap she starts to cough (it's as if her head has been in a steam room and it has loosened stuff on her chest but nothing comes up).
