Question Answer
special thing about resp system of chins?OBLIGATE NOSE BREATHERS
are they social or loners?social, live in pairs or are polygamous
what are the chinchilla teeth like?ALL of them grow continuously
how many toes in front and rear?4 in front and back
what is a defense mechanism one should be quite careful about when restraining a chinchilla?SKIN SLIP- they can have large chunks of skin come off in an attempt to get away
explain the 2 kinds of fecal pellets chinchillas have(1) Nitrogen poor- fecal pellets (2) Nitrogen rich- for cecotrophy
describe the female repro system of the chin2 uterine horns and 2 cervices, also Vaginal closure membrane open only at parturition and 2- 4 d at estrus
what kinda estrus do chins have?they are seasonally polyestrus.
what are mammaries like in chins?3 pairs- 1 inguinal and 2 lateral thoracic pairs
how do baby chins look when they come out?precocious- fully furred, open eyes, teeth present (also adult females can serve as surrogates)
what is a formula for supplemental feeding for baby chins?Evaporated milk: water 1:1 with small amount of glucose
describe the urogenital system setup in male chinsNo true scrotum-testes retained in the inguinal canal or abdomen, Inguinal canal is open, Penis is readily apparent below anus, Penis can be everted at birth
how can you determine gender in chins?male AG distance greater than female,and penis is readily apparent below anus, and penis can be everted even right at birth
what are some requirements for the enclosure you keep chins in?need solid floor, they chew so be careful of materials used, need a nest box, and are very active so need space and things to do
what temp and humidity do chins need, and what important thing must you know in relation to this? (dont worry too much about numbers)They need a Dry environment 50-68 degrees F with humidity of <50%.... important to know that they can get Heat stroke at 82-86 degrees F! (youd think weird bc in desert, but that's the case). Do NOT tolerate dampness.
how often should you give your chin a dust bath? what happens if there are too many dust baths?1-2 times a week. Too many dust baths can lead to conjunctivitis and dermatitis.
what are 4 types of dust baths you can provide?(1) blue cloud/ clue sparkle (2) Fuller’s earth (kaolin with magnesium silicate) 1:9 with silver sand (3) Perfume free talc + food grade cornstarch (4) Volcanic ash (only allow access 3-4 minutes) (usually access is ~15min, but volcanic ash is more irritating)
when are chinchillas active?nocturnal.
what kinda diet do chinchillas have?herbivorous
too many treats can cause problems-- what problems? and about how many treats is appropriate(examples of treats)?Too many treats can cause enteritis due to insufficient roughage. examples of treats are Dried fruit, nuts, seeds, raisins, figs, and no more than 1 teaspoon/day
which part of the PE do you do last?oral
why might you especially want to check the rectum of a chinchilla?impacted feces would be there
how do you restrain a chinchilla?Similar restraint to GP (gentle but firm, around chest behind front legs so animal feels secure with support underneath animal)
what are some venipuncture sites? where DONT you draw?you can use the Lat. Saphenous, cephalic, and jugular. HOWEVER, THE Cranial cava not recommended
what is the normal pH and USG of chin urine?Urine pH 8.5 with S.G. >1.045 (JUST KNOW its very basic and the USG is very high normally)
slobbers usually indicates a problem with what?malocclusion
explain how choke/bloat can happen in chins, and how we can help treat thishappens like in horses, with excess treats, or clover- it is basically clinical colic. To help, you can feed the chin Pineapple, papaya, fluids, and motility suppl. (pineapple and papaya have enzymes to break down the blocked up stuff)
diarrhea can be caused by what two types of things?overfeeding fresh foods, or infectious agents
what are the clinical signs of slobbers? prognosis?Loss of appetite --> weight loss --> decreased amount of stool. drooling. matted fur around mouth and poor coat condition. Eye discharge or nasal discharge. Fistulous track under eye, Palpable protrusion under lower jaw.... long-term prognosis is poor
explain the process behind Elongated Tooth Roots in chinchillasit's a vicious cycle. low fiber diet leads to less chewing, which causes abnormal wear and tooth elongation, teeth are forced apically (they cant grow down anymore) which leads to bone remodeling and tooth root dysplasia, leading to FURTHER elongation (Teeth can be seen to curve into sinuses, below jaw line, and even into orbits). this all results in an inability to chew properly ----> slobbers, and/or secondary abscesses
what are some things you can do to help treat elongated toothroots/ slobbers in chins?Removal of severely affected teeth and opposing teeth, Treat abscesses, Re-model malocclusions, Treat spurs, Long term pain management, Syringe feeding
Pulmonary trophoblastic emboli--> explain when this usually happens, and what happens?Usually you will suddenly find a dead chin during late gestation. what happened is that there will be an emboli in the pulmonary vessels (you might see resp. signs of distress) but then it dislodges, goes to the brain, and the chin suddenly dies
dermatologic problems are usually related to what?dust bath issues
what are three reasons a chin might be chewing its fur?thyroid dz, giardia, behavioral
three main causes of neuro problems in chins?encephalitis, lead poisoning (they chew everything), and heatstroke
what virus are chins susceptible to?human herpes 1 (dont kiss your chin when you have a cold sore)
4 bacterial infections listed that chins are susceptible to?yersinia, listeria, pseudomonas, clostridium, etc
which systemic funal infection are chins prone to?histoplasmosis
what two protozoa can chins get?Giardia, cryptosporidium
nematodes/cestodes chins can get? (4)Baylisacsaris, taenia, echinoccocus, hymenolepis**(zoonotic!)
what abx are contraindicated in chinchillas, and what can you use instead?DONT USE Metronidazole, it can cause a toxicity. use albendazole or fenbendazole instead
