Feline Theriogenology Flashcards
Ovarian cysts will cause prolonged signs of estrus. How do you treat ovarian cysts?
- hCG or GnRH to luteinize
- OHE
T/F: Some cats may cycle year round
True
Queens that live inside and are exposed to light may cycle year round
Which of the following is not true regarding cat breeding?
- They are seasonally polyestrus
- They are induced ovulators
- Are short day breeders
- All of the above are true
Are short day breeders
________ is responsible for “Kitten Mortality Complex” and “Fading Kittens”
Feline Infectious Peritonitis (FIP)
What is the treatment of choice for uterine prolapse in the queen?
manual reduction + OHE
Age of puberty in cats varies due to seasonality. What is age range of puberty?
4-12 months
-
Early season kittens may not reach puberty before the seasonal anestrus occurs
- Will reach puberty the following season when they are a year old
-
Late season kittens will mature through the seasonal anestrus
- Increasing day length will trigger cyclicity, and they may be as young as 4 months
FIV can be transmitted via milk or in utero. What percentage of kittens become infected with FIV if the queen is infected prior to conception?
~70%
When does the placenta contribute to the maintenance of pregnancy in the cat?
28-32 days
-
Progesterone is elevated 30-40 ng/mL
- The placenta will contribute to the maintenance of pregnancy starting around day 28-32 D
This stage of the estrous cycle occurs when no ovulation has taken place in a queen (not mated):
Post-estrus (interestrus)
- Period between successive estrus periods if ovulation does not occur
- No luteal tissue on ovary – no progesterone
- No sexual receptivity
- Inter-estrus period 8-10 days until next receptivity
Puberty is based on the ability of the hypothalamic neurons to produce sufficient ________
GnRH
T/F: The queen is an induced ovulator
True
Cats require prior stimulation of the perineal region or of the vulva in order to ovulate
When breeding takes place in the queen, there is a reflex release of ________ from pituitary
LH
Release of LH by the pituitary appears to be in part dependent on the duration of its prior exposure to estrogen
Roughly when does puberty occur in the Tom?
~9 months or 3.5 kgs
Testosterone production leads to the formation of spines on the penis
What is the gold standard test for pregnancy diagnosis in the queen?
Ultrasonography
- Confirms pregnancy, fetal viability information, inaccurate on count
- Can start at 14-15 days of pregnancy
- Heartbeat can be detected at day 20-25
Testicular hypoplasia is most commonly seen in ________ and ________ cats
Testicular hypoplasia is most commonly seen in tortoise shell and calico cats
Approximately how many breeding’s will ensure a 100% ovulation rate in cats?
Four
What stage of the estrous cycle is the queen in when ovulation has occurred?
diestrus
________ is responsible for cerebellar hypoplasia, abortion, stillbirth, and neonatal death
Feline Panleukopenia Virus
What is the most common cause of dystocia in the queen?
primary uterine intertia
Ovarian cysts will cause prolonged signs of estrus. How do you diagnose ovarian cysts?
vaginal cytology (cornified cells), estrogen levels, ultrasonography
Mammary hyperplasia is usually seen in the young queen (pregnant or non-pregnant) under the influence of luteal P4.
This condition usually regresses after ________
luteolysis
What hormone is commonly used for pregnancy diagnosis in the cat?
Relaxin
Relaxin is detectable at 25 days
What newer test is available to test for ovarian remnant syndrome?
Anti-Mullerian Hormone
Which of the following is not a typical behavior seen during estrus?
- Rolling over
- Treading with the back feet
- Vocalization
- Ears pinned back
Ears pinned back
What cause of abortion will likely show no clinical signs in the queen other than maybe nasal discharge?
Feline Herpesvirus
Causes abortion and placental necrosis
T/F: The queen is a long day seasonal breeder
True
What is the single most important prognostic factor for mammary neoplasia in cats?
Size
Better survival times if tumor is less than 2cm in size
Name three major teratogens in cats:
- Glucocorticoids
- Griseofulvin (antifungal drug)
- Panleukopenia virus
What is the treatment of choice for retained placenta in the queen?
Oxytocin
Absence of motility in the sperm in the semen is termed:
azoospermia
Feline herpesvirus causes pregnancy losses in queens. Which one of the following signs is typically detected?
- Cerebellar hypoplasia
- Resorption
- Abortion
- Kitten mortality complex, fading kittens
Abortion
When diagnosing pregnancy in the cat at 16-30 days, what should you feel on abdominal palpation?
“String of Pearls”
T/F: Mammary neoplasia is the most common tumor in the cat
False
- Mammary neoplasia is the 3rd most common tumor in the cat. These tumors are usually malignant and at high risk of metastasis.*
- Intact cats are 7x more likely to develop mammary tumors*
What is the typical duration of pregnancy in the queen?
~65 days
Psuedopregnancy in the queen lasts ~________ days
40-45 days
- Non-fertile mating
- Spontaneous ovulation occasionally occurs
What is the most common cause of ascending uterine infection in middle aged cats?
E. coli
