The use of megestrol acetate to stop urine spraying in castrated male cats Four castrated male cats were treated with megestrol acetate because they were showing signs of urine spraying. The dosage used was 5 mg a day for seven days followed by 5 mg every three days for 21 days. The treatment did not exceed one month.

The use of megestrol acetate in some feline dermatological problems.

Twenty-one cats were treated with megestrol acetate because they were showing clinical signs associated with one of the following problems: eosinophilic ulcer, eosinophilic plaque, neurodermatitis, endocrine alopecia and miliary dermatitis.

Intradermoreaction and hyposensitization in canine atopy.

Results obtained from allergic skin testing and hyposensitization in 81 dogs are discussed.THE POSITIVE REACTIONS ENCOUNTERED MOST FREQUENTLY WITH INTRADERMAL TESTING WERE: house dust (88.9%), cotton (59.3%), moulds (53.1%), biting insects (47.0%), feathers (37.0%), kapok (35.8%) and grasses (35.8%).Only dogs with constant and multiple sensitization were hyposensitized.
