seasonal WL. 40% in summer. and hair thins out
clinical exam of a ferret?
what common dental problem do they get?
why should you certainly assess the mm?
what are ear mites?
in a female - vulval swelling? what does neutering predispose to?
dont like temp being taken,
dental - commonly - tartar and gingivitis.
mm assess in females for anaemia - to do with oestrus toxicity.
ear mites - otodectes cynotis) brown and waxy
splenic enlagre is common? - can be normal.

where can you admin drugs?
iv - cephalic, jugular, later saph

1% bw = safe. to take bloods. need AN. can take from heart too as further back.
blood sample sites and amount? 1% safely. need AN.
cephalic - 1ml

skin diseases? most common? where?
otodectes cyanotis. ear mites, outer ear canal. ivemectin!
flease- from cats and dogs. do not spray fipronil - put on cloth and then ferret.
do not use collars as they are toxic.

neoplasia? most common? (2)
mct - usually benign. well circumcised, may be ulcerated.
sebaceous epithelioma/adenoma - pedunctualted/plaque like mass. may become ulcerated.
misc ?? - to do with sebaseous glands? cx?
sebaceous glands - naturally musky odour and greasy feel. normally coat thins in warm weather. and bilaterally sym alopecia of tail perineum and inguinal in breeding season.
adrenal gland disease? associated to?
what may predispose it?
what can you use to control this?
associated to adreno cortical neoplasia. adenoma. etc.
neuter - correlated. leads to concerns.
could use deslorelin implants every 18m/o.
cx - bliateral alopecia, pruritis, vulval swelling. castrated male.
dx - us - enlarged, assay - androges, osetrodiol, ANDROSLEINDIONE.
ddx - ovarian remenants.
tx - surgery and medical. if both remove one and abit of another. unilateral - remove one and recover. may use deslorehlin implants (gnrh)
hyperoestrogenism? common when and in who?
side effects of oestrogen?
tx? - many ways?
females in the breeding season - mar-sept.
if unmated - 50% get aplastic anaemia - look at mm. after a prolonged oestrus.
oestrogen - suppresses BM. - anaemia and pancytopaenia. may be due to adrenal neoplasia?
cx - swollen, vulva, vulval discharge, anorexic, pallor, systolic murmur, weak pulses, meleana, alopecia at tail base, petechiation, posterior paresis, systemic infections due to leuopaenia. paresis - due to haem myelomalacia.
dx - h and cx and haem.
tx - support when not in season, - iron and vit b and abs,
HCG - makes ovulate?
jill jab - proligestone - prior to start of breeding season? - side effect sof pyo ansd liver disease and skin reaction need to give every year.
deslorelin - last 2 years. overcomes risks of AGD if you have spayed. need to repeat
mate with a hob - may get bites. every time comes into oestrus.
artificially keep day length short - unreliable.
spay - permanent! good. but risk of AGD within 3. 5 years. lack of feedback from LH and FSH. implant deslorelin. prevents but need to do every 2 years.
insulinoma? usually seen in? cause by which cells?
- prog? surgery? or meds?
middle aged ferrets? b-islet cells affected. high insulin produced leads to hypoglycaemia.
cx - collapse, recumbent, dep, salivate, glassy eyed, - acute
chronic - weak, leth, ataxic, wl, inapp.
dx - h and cx. low blood glucose levels. and normal of high insulin.
tx - surgery or meds. prog - 6-24 m/o
meds - preds/diazoxide. orally 2xd.
monitro blood glucose. feed regulary with high protein and fat diet. feed snack after sleep due to low blood glucose.
Gi diseases? obstruction?
what is a trichobezoar?
fbs are common. trich - hairball.
vomit and regurg amorexia, leth, wl ,diarr, ptyalism, paw at mouth, hard to palpate stomach as in ribcage.
dx - xrays and contrasts
tx - surgery laxatives for hair balls.
toxocaris cati/ dipylidium caninum? giardia

3 viruses seen in ferrets?
1) distemper? cx?
2) aleutian disease? parvo, cx, dx,
3) influenza? cx? tx?
1) distemper - vacc! cx - chin rash, dermatitis, anorexic, pyrexia, dep, photophobia, blepharospasm, discharge, cough and sneeze. 2 bacterial. hyperkeratosis. cns signs. fatal. trans by aerosols.
2) aleutian disease - ferrets. parvovirus. cx - ataxia, paresis, paralyss, tary faeces, wl.
dx - histo, liver kidney spleen, meninges (lymphs) PTS,
3) INFLUENZA - cx - similar to distemper. serous nasal discharge. cough and sneeze. self limits ans support.
2 main kinds of neoplasia seen? other 2 - insulinoma and AGD.
1) lymphoma? 2 forms? cx? dx? tx?
2) splenomegaly? due to? if under 3 years? assess what before surgery? why?
lymphoma - 3rd most common after insulinoma and AGD.
1) juvenille - lymphoblastic - more aggressive
2)adult - lymphocytic
cx - imapp, lns, pleurla effusion, dyspnoea, cough and organ enlarge.
dx - xray, us, fna, lns, biop lns, thoracocentesis, cyto, haem.
tx - thoracocentesis, nutrition, steroids, doxorubicin, radiation and vincristine, bad prog - 6m/o.
b) splenomegaly - extramedullry haematopoesis. neoplasia. unde r3 yrs old - more likely to be neo. surgery to remove but check BM function before as it may be a main site of erthropoesis?
what must you do to ferrets before AN that you dont do with any other rodents?
starve - 4-6 hours.
diazepam, atropine, acp, midazolam, hypnorm.
medetomidine and ket.
alfaxalone, ket/acp, ket/diazepam, med/ket/bupre, hypnorm and midazolam.
inhaled AN? when normally used?
iso/sevo. esp if fractious. prior sedation is good. easily intubated.
bupre (8-12 hours) plus reverse hypnorm while still have analgesia.
antipamezoles - reverses alpha 2.
nsaids or LAs. also good.
surgery - OVH? best to do when? how can you prevent AGD?
may predispose to AGD. best to do before 1st osetrus. midline approach. dont need to break ligs as they are very lax. use deslorelin implants to prevent AGD.
castrate? predisposes? when to do? why do it?
keep apart for how long? how can you reduce AGD? reduces odour.
not routine. predisposes AGD. 6-8m/o good.
reduces aggression and sebaceous gland secretions.
leave open. inguinal canal is closed.
keep apart for 6 weeks. use deslorelin implants to stop AGD. need every 2 years.
vasectomy? good to use for? how done? retains ferrets urge to mate. infertile.
use to bring females out of oestrus. reflex ovulation prevents - persistent oestrus. and hyperosetrogenism.
dorsal recumbency. - deep layer of sc fat. avoid urethra. one end uture to tunica to prevent anastmosis, nsaids. 2 pre scrotal incisions. palpate cord 1st.
