Dealing with Cat Tear Stains
Tear overflow (epiphora) happens when tears overproduce or the nasolacrimal duct blocks, spilling onto the fur. The reddish-brown stain comes from porphyrin—an iron waste in tears that oxidizes in air and sunlight. Common causes: too much salt (human food, salty kibble), 'heat', ear infections that stimulate tearing, duct blockage, entropion (inward lashes), dacryoadenitis, and feline herpes (tears plus nasal discharge—watch unvaccinated cats). Genetics play a role too. Cut salty food and see a vet to find the true cause.
What Causes Glaucoma in Dogs?
Canine glaucoma comes in primary and secondary forms. Primary glaucoma is a hereditary drainage-angle defect that blocks fluid outflow and raises eye pressure; it is common in Huskies, Chow Chows, Poodles, Cocker Spaniels, Beagles, and Maltese, usually appearing at 4–9 years. Secondary glaucoma follows eye disease such as uveitis, pupil blockage, lens luxation, or tumors. Treatment aims to lower pressure and save vision—medication works best early, but surgery is often needed later. Because early signs are subtle, at-risk breeds should have annual eye-pressure checks.
White-lipped Mud Turtle
A strikingly pretty mud-turtle relative - the 'mango-head' morph can flush yellow onto limbs and shell. Friendly and mid-priced, but it cannot brumate and must be kept heated year-round.
Central American Snapping Turtle
The rarest of the four chelydran snapping-turtle subspecies - large, dark, pugnacious, and really a 'meat turtle', not a home pet.
Hundred-pace Viper
The Hundred-pace Viper (Deinagkistrodon acutus) is a highly venomous pit viper from southeastern China and Taiwan, nocturnal and storied in Asian folklore. Extremely dangerous, it is not suitable for home keeping.
Kinosternon acutum (Tabasco Mud Turtle)
The Tabasco mud turtle (Kinosternon acutum) is a medium-sized mud turtle prized for its vivid head striping, found mainly in the Mexican Caribbean lowlands. It is rarer than the narrow-bridged musk turtle and seldom seen on the market.
Graptemys pulchra (Alabama Map Turtle)
The Alabama map turtle resembles the red-eared slider in habits, with head striping and a protruding keel. Named for its map-like yellow markings, it feeds mainly on aquatic clams and snails, crushing shells with its hard jaws.
Stripe-necked Leaf Turtle
The Stripe-necked Leaf Turtle (Cyclemys tcheponensis) has a broad distribution and healthy wild populations, and even wild-caught individuals adapt well to human care. A semi-aquatic species, it favors shallow water adjoining land; adults prefer fruit while juveniles lean toward meat.
Canine and Feline Nasolacrimal Duct Obstruction (Epiphora)
Nasolacrimal duct obstruction blocks normal tear drainage in dogs and cats, causing chronic epiphora (tear overflow) and facial staining. Congenital duct atresia usually needs surgical correction, while acquired obstruction from conjunctivitis or injury is managed by treating the underlying cause.
Canine and Feline Glaucoma: Symptoms, Treatment, and Prevention
Glaucoma is raised pressure inside the eye of dogs and cats from blocked fluid drainage, damaging the retina and optic nerve and risking blindness. It is managed with pressure-lowering drugs and, sometimes, surgery.
