  137. rabbit diet
    • Pellets 20% or less (Timothy based for adult)
    • grazing 50% of diet (hay, little/no alfalfa, fresh untreated grass
    • 30% veggies
  138. Rabbit restraint
    • Spinal injury from kicking--just set them down if kicking, keep non-slip surfaces.  Cover eyes if stressed (hold like a football with full-body scruff.
    • Don't "hypnotize" on back by rubbing belly, cortisol spikes and they panic.
  139. Rabbit PE
    • No menace, no tapetum. Tympanum easily ruptured and straight canal, flush GENTLY.
    • Dewlap in females to pluck hair and line nest.
    • Oral - DENTAL ISSUES.  Peg teeth behind, 2 upper and 1 lower incisor. Oral speculum or otoscope cone for cheek teeth. Palpate for elongated roots in cheek teeth.
    • Loud lung sounds, can listen to heart on sternum. Huge heart, murmurs heard everywhere
    • stomach should always be full
    • black waxy material in inguinal scent glands.
    • Temp should be >100, below is shock!  Therm DORSAL
  140. Bunny venipuncture
    • Small samples: marginal ear vein (poke and let drip, catheter), cephalic vein (good for cath, only straight one in body)
    • lg samples: lateral saph (cath), jug vein (don't lift head too high)
  141. bunny fluids
    SQ warmed isotonic along shoulders/back/laterally

  143. How is rabbit GI like a horse, and how not?
    Hind-gut fermenters (except make night feces)
  144. rabbit dentition
    • Not enough fiber = small cheek teeth chewing, need more to avoid points
    • can't prehend/drop food
    • ulcers as the teeth grow into other tissues.  Can trim teeth - low speed to avoid HEATING teeth up. 
    • As teeth grow up, too much pressure will make them grow DOWN = abscesses (anaerobic). Debride and pack, open and marsupialize, etc.
  145. Gastric stasis in rabbit, guinea pig, chinchilla
    • indicates DRIED OUT material in stomach--decreased consumption, low fiber, high carbs (hair is normal, but hairballs)
    • USU BAR but hx of anorexia, small hard feces or no feces, doughy mass in cranial abdomen (halo in rads pathognomonic)
    • tx: rehydration of P, rehydration of stomach contents, increase motility.  Fluids, force-feed high fiber or critical care or pumpkin, metoclopramide or cisapride, fresh veggies and hay, respond in 2-4d
  146. Goals in GI stasis of rabbits
    • rehydrate P
    • rehydrate stomach contents
    • increase gastric motility
  147. gastric obstruction in rabbits
    • Hairball, FB, pyloric disease, rabbit seems SICK, often hypothermic.  Stomach taut, full, fluid or gas. No halo on rads.  Emergency!
    • tx metabolic (acid/base)  and stomach distension (pushing on diaphragm, can't breathe!). = fluids, heat, gastric lavage, sx with FB.  
    • Metaclopramide and small food q2h
    • guarded prognosis
  148. Dysbiosis in rabbits
    Unbalanced flora.  Caused by some abx -  penicillins, macrolides and cephalosporins PO
  149. diarrhea in rabbits
    • Older: Often just uneaten cecotropes
    • low fiber, high carbs, stress, oral abx and bacterial enteritis (clostridium, usually secondary).
    • Young: unestablished GI flora.  Coccidia, corona or rotavirus, bacterial (clostridium, salmonella, pseudomonas, campylobacter, E. coli, C. Piliforme
  150. rabbit URI
    • "snuffles"
    • check uppper legs--grooming. Nasal culture helpful.  
    • Systemic and topical abx.  
    • Can also have allergies.
  151. Uterine neoplasia in rabbits
    • 80% unspayed females by age 4
    • adenoma, adenocarcinoma, endometriosis, hyperplasia, uterine aneurysms, pyometra. Thx with OHE.  Lung mets common.
  152. Rabbit neoplasia
    • Thymomas: exophthalmus, exercise intolerance, lethargy, dyspnea, hiccups.  
    • Sx or radiation
  153. rabbit, guinea pig, chinchilla urinary tract disease
    • Ca sludge in bladder, stones common (bladder, ureter, kidney).  Bladder feels like hacky-sack, urinate sludge.  Rads.  
    • Remove when possible, or potassium/sodium citrate to reduce size and preventative.
  154. torticollis/wry neck in rabbits
    • peripheral vestibular disease: bacterial infection of bulla through eustacian tube, bulla osteotomuy(+/-TECA), long-term abs
    • Central vestibular disease: encephalitizoan cuniculi, or other CNS stuff.  Tx with meloxicam and albendazole/fenbendazole. Headtilt may never go away, roll
  155. Guinea pig life span
    5-7y
  156. How to tell a guinea pig is dehydrated
    Sunken eyes
  157. guinea pig head butt response
    touch forehead and they push off--otherwise depressed
  158. guinea pig auscultation
    Heart cranial, over sternum, LOUD lung sounds like rabbit
  159. abdominal palpation in guinea pig
    stomach often empty (2h), can palpate kidneys, third kidney is likely an enlarged ovary (>3y very common)
  160. chinchilla restraint
    • support body
    • hold base of tail - jumpers!  
    • Don't grab fur--fur slip!
  161. Chinchilla PE
    • Palpate jaw line for root elongation
    • familiar heart murmurs normal, loud lung sounds.  
    • Sex via anogenital distance.
  162. Guinea pig  diet
    • need vitamin C so FRESH pellets
    • high fiber diets
    • Timothy or grass hay 50% diet. Fresh veggies up to 30%.  Won't try new foods when older
    • dirty, need sipper bottle
  163. chinchilla diet
    Commercial pellets <40% of diet with free choice Timothy or grass hay, 10-25% veggies, sugars and treats <5% of diet
  164. Chinchilla/guinea pig venipuncture, fluids
    • cranial vena cava
    • jug (more lateral than expected), don't tilt head too far (asphyxiate)
    • catheter in cephalic or lat saph
    • 60-100ml/kg/day
    • dorsal to scapula, not much space so many pockets or frequent
    • IM in small volumes in caudal thigh, no epaxials in chinchilla
  165. Guinea pig, chinchilla dental disease
    • Lingual entrapment: teeth grow over tongue, can't swallow
    • abscesses less common than rabbits
  166. dystocia in guinea pigs
    • moms >7mo old.  OK to breed first time before 6mo (pelvic symphysis closes).
    • tx with oxytocin if going to fit, C-section if not (not a good prognosis)
  167. guinea pig pregnancy toxemia
    • Older, obese sows before or after parturition
    • ketosis, depression, weakness, dyspnea.  Hypoglycemia, ketonemia/uria. 
    • PREVENT, tx doesn't always help
  168. cystic ovaries in guinea pigs
    Sows 2-5y, alopecia, pruritus, abdominal masses. Only 1 type of cyst is hormonally active, too much hormone = uterine disease.
  169. guinea pig BCS
    Fat around armpits or chin = obese
  170. Rodent restraint
    hold by BASE Of tail, can full-body scruff (make the hamster smile), often better walking around
  171. tumors in rats and mice
    Mammary tumors!!!  If it's not on the head in a rat, it's a mammary tumor.  Usu benign in rats (fibroadenomas), malignant in mice.
  172. Resp in rodents
    mycoplasma pulmonis - CHRONIC, persists for life.  Enroflox and doxy, maybe azithro.  Thx for 2 weeks, lone for 5 months, recurs.
