Feral cats are fiercely independent and survive (but may not thrive) without the help of humans. They avoid people and hide, back away, or flee when they spot humans. Lack of immunization, parasite control, adequate nutrition, and hygiene put feral cats at risk of many life-threatening problems. TNR (Trap, Neuter, and Release) programs are the hallmark of controlling feral cat populations.

Mast cells are a type of white blood cell that plays a large role in allergic response through degranulation. Mast cell tumors (MCT) can occur in the skin, spleen, or gastrointestinal tract of cats. Their cause is unknown; however, many affected cats show a genetic mutation in the KIT protein involved in replication and cell division. Cutaneous MCTs most often appear as hard pale/white plaques or nodules, often around the head and they may be itchy. Splenic MCTs cause decreased appetite, weight loss, and vomiting. Intestinal MCTs may cause GI upset and bloody stools, and a mass may be palpable. Diagnosis is typically achieved via fine needle aspirate although histopathology can be used. Treatment usually requires surgical removal of the masses or the spleen. Sometimes, chemotherapy or radiation is needed.

Masturbation behavior in male parrots is a fairly common occurrence. The basis behind this activity is sexual stimulation or over productive male hormones. Veterinary attention will help with environmental changes and/or medications used to diminish or halt this behavior.

Megacolon is extensive stretching of the colon and resulting constipation. It occurs when the nerves to the colon do not function normally, causing the muscles of the colonic wall to not contract properly. The muscles then become stretched over time and the colon enlarges in diameter. Fecal material accumulates in the distended colon, resulting in severe constipation called obstipation.

Melanomas are cancerous growths of the cells responsible for pigmentation of the skin. They can develop anywhere on the body but those on the toes carry the highest chance for malignancy. They may be painful and you may notice your pet licking at the affected area. Surgery is often the treatment of choice and may be followed up with radiation or chemotherapy.

Melioidosis is a bacterial infection that is typically associated with tropical regions. The bacteria that causes melioidosis, Burkholderia pseudomallei, is usually found in soil and water. The clinical signs of this condition, along with transmission, diagnosis, treatment, and prognosis, are outlined in this handout.

Meningoencephalitis is a term referring to inflammation of the brain and the surrounding fluid and tissues. Meningoencephalitis of unknown origin is a term used to describe those cases of meningoencephalitis in which MRI and cerebrospinal fluid analysis indicate the disease but diagnosis through histopathological analysis is not possible. Treatment typically involves immunosuppressant drugs, sometimes with the addition of antibiotics. The prognosis depends on several factors, which are also explained in this handout.

Milbemycin oxime + lufenuron is a heartworm disease preventive that also treats internal parasites (e.g., whipworms, hookworms, and roundworms) and controls flea populations in dogs. Milbemycin oxime + lufenuron is given by mouth as a flavored chew tablet. At prescribed doses, this medication is well-tolerated; when used off-label at higher doses for treating mites, side effects have been observed. Your veterinarian will advise you on the safety of milbemycin oxime + lufenuron use in your dog. If you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately.
