Spaying and Neutering Guinea Pigs


For a variety of reasons, veterinarians do not recommend that owners attempt to breed their guinea pigs. One concern is that breeding will produce more guinea pigs than available homes. As with most companion animals, there are many homeless guinea pigs available for adoption in animal shelters.


Another concern of veterinarians is that the female, also known as a sow, can experience complications during the delivery of her offspring. These complications are caused by the stiffening of the pelvic …

How often should I give my chinchilla a dust bath, and what is the best way to go about that?

Chinchillas in the wild take frequent dust baths to help absorb skin oils and dirt from their fur to keep their coats clean and healthy. Use only commercially manufactured chinchilla dust, as it is made to imitate the dust in their natural habitat. Make the dust bath available to your chinchilla two or three times a week, preferably in the evening when chinchillas are most active. Leave the dust bath in the cage for 10 to 15 minutes. If left …

Barbering in Companion Rodents

Barbering results in alopecia (loss of …

Dental Care for Companion Rodents

The scientific classification order that all rodent species belong to is called Rodentia, which means “to gnaw” in Latin. Rodents have teeth (incisors and molars) that grow throughout their lives. In the wild, these animals gnaw on materials such as wood and forage to keep their incisors worn down to an appropriate length. Domesticated rodents such as mice, rats, chinchillas, and guinea pigs also need to gnaw on materials to keep their teeth worn down. If the incisors are …

Canary Care

Canary Bird 01


Canaries come in a variety of colors and types. They are generally classified in three basic varieties: song, color, and body type. Song canaries are bred for their singing ability, with the more intricate and melodious songs being desired. Although only male canaries sing extensively, females are sometimes known to sing quite well, making it difficult to differentiate the sex of the birds. Color-bred canaries are bred for their red-factored feathering, which is made darker through the consumption of …

Ectoparasites: Fleas

Fleas are wingless insects and cannot fly, but they are capable of jumping as high as 2 feet. Adult fleas feed exclusively on the blood of …

Canary Breeding


Breeding canaries can be a fun and interesting hobby. For beginners, the breeding-type canaries, such as glosters, are the easiest to start with because they breed more easily than some of the color and song varieties. Hen canaries are much less expensive than males because they do not sing as well, and a good selection should be readily available from hobby breeders.
