  • Children often have very close relationships with pets, and especially with cats. Losing a pet cat is inevitable and may be the child's first experience of death, but there are ways for parents and others to help the child cope with it. Start by talking with your child about death truthfully and in an age-appropriate manner. It is important for children to have the chance to say goodbye. Children grieve just as intensely as adults do, but often have different ways of expressing their grief. Each child will grieve their cat in their own unique way and at their own pace. With care and support, your child can grow through the grief and heal.

  • Chin acne in cats is a poorly understood disorder of follicular keratinization (the overproduction of keratin, a protein found in the outer layer of skin). If this excess keratin is trapped in the hair follicle, comedones (blackheads) form. Pustules (pimples) may form if bacteria infect the comedones. The underlying causes are not fully understood but may be associated with excess sebum production, viral infection, immunosuppression, stress, or poor grooming. Treatment options are available and often involve improved hygiene.

  • Chlamydial conjunctivitis in cats is highly contagious and can look similar to herpes conjunctivitis. Young cats and kittens are especially vulnerable to this infection, although chlamydia can be detected in cats of all ages. It is one of the most common causes of infectious conjunctivitis in cats. This handout describes the clinical signs and how this condition can be treated or prevented.

  • Chlorfenapyr poisoning is suspected if a pet has access to this pesticide and subsequently develops expected signs; it should also be suspected in a pet exhibiting signs and at risk of malicious poisoning.
