Currently, more pediatric spays and neuters are performed in animal shelters and humane societies than in small animal veterinary practices. General practitioners are more likely to be asked to perform early age altering by breeder clients than the average pet owner. Many breeders now prefer to sell only altered kittens as pets. In a recent informal survey of cat breeders, about 70% of those surveyed held the opinion that access to early altering was important to them (Little S, unpublished data, 2000). Another benefit is kittens that require elective surgery for other reasons (i.e. hernia repair) may be early altered at the same time.
