Vocalizations - guinea pig

Guinea pigs make a variety of noises, some of which most guinea pig owners will recognize. Contented guinea pigs just going about their day often make a variety of squeaks, chortles, and quiet grunts. • Wheeking: This is a distinctive and common vocalization, and is used to communicate excitement, particularly about being fed or simply a call for attention. It sounds like a long, loud squeal or whistle. • Purring noises: These have different meanings depending on the pitch of the sound. Guinea pigs that are feeling contented and comfortable will make a deep sounding purr. A short purr may indicate fear or uncertainty • Rumbling: This is a deeper rumble than the purr. This noise is made by a male romancing a female, and sometimes also by females in season. While courting, a male usually purrs deeply, swaying and circling the female in a behavior called "rumble strutting". This is also called as motor boating. • Teeth chattering: This is a sign of an agitated or angry guinea pig and is an aggressive vocalization. It is often accompanied by showing the teeth and means "back off" or "stay away." • Hissing: like teeth chattering • Cooing: It communicates reassurance and is a sound most often made by mother guinea pigs to their young. • Shrieking: A piercing, high pitched squeak that can be mistaken as a call of fear, or pain. If you hear this type of sound, it is good to check on your guinea pigs to make sure everything is okay. • Whining: a whining or moaning type of squeak can communicate annoyance or dislike for something you or another guinea pig is doing. • Chirping: Sounds just like a bird chirping; this is perhaps the least well-understood noise guinea pigs make.

BURN INJURIES

BURNS – Burns are injuries, which result from exposure to extreme heat, flame, inhalation, and scalding, chemical or electrical trauma. Burns can produce clinical syndromes ranging from self –limiting injury to long term incapacitation and finally death. Disease forms:- a. First - degree burn – superficial layer of dermis is involved, which is red, dry and painful. b. Second-degree burn – superficial layers of dermis is involved and is red, wet and very painful. c. Third and Fourth-degree burns – in third degree superficial layer of dermis and in fourth degree subcutaneous layers, bone and tendons are involved. Appearance is waxy and leathery and is less painful than first or second. These degree burns causes a great risk of wound sepsis, coagulation disorders, ventilator compromise or abdominal problems. Clinical signs depend on the location and extent of the burn and may vary from hypothermia, shock, and dyspnoea, pharyngeal and laryngeal oedema, corneal trauma. Diagnosis can be made on the basis of CBC, serum profile, coagulation panel, radiographs and culture. Prognosis is generally good with first and second degree burns and more guarded with third and fourth degree burns. Prognosis improves with appropriate and successful wound management.
