Yesterday we had to put the cat down. Princess Bell Bell had a traumatic life before Jules rescued her from a shelter in Georgia. She traveled with him across the country and was very much his girl. However, she has had skin issues for years and neurotically licked herself. About a year ago she was pulled off all grains thinking it was an allergy and that seemed to help. Then had a complete freak out resulting in steroids to get her to stop attacking her skin. After that, she never seemed to quite heal.
She developed mites. They went undetected by the vet for quite some time and eventually I turned to the Internet to try and figure out what she had. At a certain point, they can't be cured and the pet has to be put down. Mites are one thing that I never want to learn more about. Apparently (and disgustingly!) they are constantly on our pets and even us with no one really knowing much about it. It is only when the immune system gets suppressed or when the populations get extremely high that there are nasty break outs. Once there is a break out, it is extremely contagious. Eeew!
The cat gave them to the dog. Only in a small place and it can be treated since we caught it right away. However, it means the entire house has to be washed, disinfected, completely scrubbed.
