Are some fish poisonous to eat?
The Puffer fish and the fugu fish — these can kill you within minutes of eating them and many people have daredevil bets when they eat them. But all fish are potentially poisonous. They have the highest amount of Polychlorinated Biphenyls or PCBs, which are carcinogenic. They are full of mercury and pesticides and all fish have a great deal of human faeces in them. All this goes into your own body. This may not kill you at once but certainly the body weakens and becomes open to many more diseases.
Is the vision of red eyed rabbit normal?
Yes. Albino rabbits aren’t that different from other rabbits — they just lack colour pigment. Their eyes are red because you are seeing blood vessels because there is no colour to cover them. Their eyes work the same except they tend to let in more light, so they sometimes have problems focusing and might not like bright light. Red eyed rabbits often move their heads from side-toside scanning to help them see things better.
Our neighbour uses salt in his kitchen garden for snail-free crops. Do snails die when salt is poured over them?
Slugs and snails have a higher percentage of their body weight made up of water, than other animals. Also, their skin is a much more permeable covering than average. When you salt a slug or snail, this increases the concentration of salt on the surface (outside) of the poor snail and decreases the water concentration outside the slug/snail. The process of osmosis is the movement of water from an area of high water concentration through a permeable membrane to an area of lower water concentration. The water inside the slug moves outside the slug, in order to reach an equilibrium concentration on both sides of the skin. Unfortunately, this means that the slug/snail is now much drier then it can tolerate. It literally dies of dehydration. But salt is really bad for the garden soil. Salt causes soil to become more acidic, altering the ionic exchange capability of the soil. This, in turn, affects the soil’s ability to transfer nutrients to plants. Salty soils cause plants, including your grass lawn, to become nutrient deficient because they don’t pick up enough of the nutrients they need, such as nitrogen and phosphorous. Subsequently, plants don’t grow as well, and important nutrients are leached out of the soil into the groundwater.
My dog has a lot of wax in his right ear and always keeps shaking his head. Is that a sign of an ear infection. What can I do at home to relieve him?
You have not mentioned important factors in the diagnosis, such as the colour and frequency of discharge if any, how often the ears are cleaned, how often your dog is in the water and more. Ear problems are one of the most common ailments dogs are taken to vets for, and can be caused by infection, trauma, parasites and various other reasons. The first sign of a problem is usually ‘excessive’ wax production or discharge. In many dogs, a little discharge is normal: compare the ears to see if one is producing significantly more that the other. Head shaking and scratching is the next sign, and this is when yeast or bacteria has started to feast on the excess wax. Dogs with floppy, hairy ears and dogs that swim may be predisposed to developing ear infections. Diagnosis by your vet will usually include an xray of the middle ear and a culture of the bacteria found in the discharge to determine the best treatment. If your dog is floppy eared who is always playing in water, either reduce his water time or make sure you clean and dry his ears properly. Take a moist cotton ball and gently rub away visible dirt from the ear lobe. Using a moist QTip, next clean between the protruding cartilage of the ear, being careful not to probe the ear canal. Never put the Q-Tip in too deep. Towel dry the ear and apply an ear-drying powder to prevent problems.
