What is a false pregnancy in rabbits?
A false pregnancy in rabbits occurs when a doe shows signs of pregnancy - such as swollen mammary glands and nest-building - without actually being fertilized. It is usually caused by poor sperm quality, lack of mating experience, or hormone injections.
Can Cats Tell Men and Women Apart?
Cats don't grasp the social idea of gender, but they do tell people apart by scent, sound, and body size. Their smell is about 14 times keener than ours, picking up human hormones and pheromones — including pregnancy and menstrual changes — so a cat may sense a woman is pregnant or cycling before she realizes it.
Do female cats have a menstrual period?
Female cats do not menstruate. As induced ovulators, they show only behavioral changes in heat, and any unfertilized eggs are reabsorbed, so there is no cyclical bleeding.
How to Tell If Your Cat Has Miscarried
Early in pregnancy a miscarriage is subtle — occasional pink discharge and a slight drop in appetite. After a month, when the kittens are formed, you'll see heavy red discharge with abdominal pain, cramping, lethargy, and poor appetite; a premature birth yields very small live or dead kittens, even mummified ones. After any miscarriage, see a vet for X-ray or ultrasound to confirm the placenta is fully expelled and prevent infection.
Is Pyometra Common in Dogs?
Pyometra, a pus-filled uterus, is fairly common, especially in older unspayed females. It usually starts from a bacterial infection, most often E. coli, that takes hold when the uterine lining is thickened and the dog's resistance is low, helped by high progesterone levels and unstable heat cycles. The most reliable prevention is spaying. Keeping the environment clean, avoiding progesterone-based heat suppression, and treating early uterine inflammation also lower the risk.
What to Do When Your Cat’s Temperature Drops to 37°C
A normal cat temperature sits between 38.5°C and 39.5°C, so a reading of 37°C is below the healthy range and worth taking seriously. The right response depends entirely on the cause. Sometimes it signals a weak or sick cat that needs warmth and a vet; other times it is a normal, expected dip just before labor. Here is how to tell the difference.
Mammary Tumors in Dogs and Cats
Mammary tumors are common in intact female dogs and are the third most common feline tumor. They often appear as firm nodules in the mammary chain and can ulcerate or spread to lymph nodes and lungs. Early spaying sharply lowers risk, and surgery is the main treatment.
False Pregnancy in Dogs and Cats
False pregnancy is a hormone-driven syndrome in which an unbred female shows pregnancy-like signs such as nesting, lactation, and behavior change. Mild cases resolve on their own, but pyometra must be ruled out; hormone therapy or spaying helps recurring cases.
Why Does My Dog Have Frequent False Pregnancy?
False pregnancy usually comes from a long corpus luteum phase that keeps hormone levels high. It can also signal reproductive disease like endometritis, hydrometra, or pyometra, which disrupt progesterone. Frequent cases need a vet check for reproductive disease.
