What are a rabbit’s characteristics?
Rabbits have long upright ears, large lively eyes, 180-degree monocular vision, and a typical three-lobed mouth. They are nocturnal, resting by day and most active and feeding at night. Their incisors grow continuously, so they must chew to wear them down or risk oral disease.
Mountain Hare
The Mountain Hare (Snow Rabbit) is a hare of cold regions whose coat color differs between winter and summer. It is the only completely color-changing hare still found in China, with greater numbers in Heilongjiang. Timid and easily startled, it is difficult to keep in captivity.
Amami Rabbit
The Amami Rabbit, also known as the Ryukyu rabbit, is an ancient wild rabbit with short ears, native to Japan and considered a living fossil and close relative of the Arctic hare. It is listed as Endangered (EN) on the IUCN Red List.
Slow Loris
The Slow Loris (Loris tardigradus) is a small prosimian of the family Lorisidae and genus Loris. It is nocturnal, moves slowly, and prefers to rest atop tree branches. In recent years, due to habitat destruction, hunting for use in traditional medicine, overhunting, and its own biological traits, it is on the brink of extinction.
Rabbit Vitamin A Deficiency
Vitamin A keeps rabbit mucous membranes intact and vision sharp; deficiency, worst in winter and early spring, brings slow growth, weak coat, nerve signs, eye damage (conjunctivitis, keratitis, even ulceration), and in pregnant does premature birth or dead malformed kits. It stems from low-carotene feed, poor gut or liver absorption, or vitamin loss in storage. Diagnose by history, lesions, and plasma vitamin A below 0.2 to 0.3 mg/ml.
Why Do Cats Stare at the Wall?
It is normal for a cat to stare at a blank wall - it may have seen or heard something that caught its attention. An occasional episode is usually nothing to worry about, but if your cat stares at the wall often and shows other unusual behaviors, take it seriously and have a vet check it to rule out illness.
What if a cat gets too much taurine?
Excess taurine does little harm since it is water-soluble and excess is excreted; short-term overdose is not worrying. Deficiency, however, causes night blindness, weaker immunity, and poor reproduction, so supplement regularly.
Can bats really not see?
Bats can see, but their vision is weak, and since they are active at night they navigate by sound waves (ultrasound too high for humans to hear). Because they live in dark places, they are light-sensitive; strong light bothers their eyes, so to remove a bat indoors, turn on the lights to scare it away.
Feeding Your Cat Chicken Liver? Watch Out for Vitamin A Toxicity
Vitamin A is vital for cats but fat-soluble, so excess is stored and builds up to toxic levels — usually from too much liver or stacked supplements. Chronic toxicity causes stiff gait, joint pain, dry skin, coat loss, and gut upset, and the bone damage can be permanent. Feed liver only as an occasional treat and rely on a balanced AAFCO/FEDIAF complete food.
Why a Schnauzer May Not Be the Right Dog for You
Schnauzers are clever, brave, and cheap to feed, but they are not as easy as they look: they bark when left alone or visited, they are smart yet stubborn, they have sensitive skin prone to allergies and infections, they carry hereditary risks like progressive retinal atrophy and intervertebral disc disease, and their long coats need regular grooming. New owners should think carefully.
