版主, 唔止咁少, 俾個網址你過目, 雖然香港冇幾何有機會俾狗狗咬到植物, 又例如好多人都唔知貓狗唔食得提子 (因為有幾種乾糧都有提子精華)
Homemade 果部份又係唔係一定要有骨在內 ?
如果每日 Homemade 果部份都用淨肉可以嗎 ?
咁如果每餐都只餵 Homemade 的話, 又係唔係餐餐都要加返內臟同菜 ?
平時會用蘋果, 蘿白, 青豆, 菜心, 白菜仔, 生菜...咁仲有咩果或菜可以餵 ?
西瓜, 木瓜, 哈密瓜, 士多啤梨, 奇異果, 菠蘿, 香蕉, 番茄, 冬瓜, 節瓜, 青瓜, 勝瓜, 茄子, 椰菜, 通菜, 芥蘭 ... 等等

Speaking to this, let me say that almost any nutrient or food in excess can be poisonous and that clearly, some animals species (and individuals within species) are more sensitive to certain compounds contained in some foods compared to others. The degree of sensitivity does depend on their detoxification system (mostly in the liver), whose functions are in turn dependent upon the Evolutionary background of the animal in question. Salt is a toxin in excess, as is protein, fat and water. Kelp, which may be thought of as a marine version of Medicago sativa (Alfalfa or Lucerne) is toxic in excess – both for its salt content and its iodine content and probably for other reasons as well. Indeed, most whole raw vegetables contain toxic materials and that includes refined carbohydrates – these too in excess act as slow poisons, compromising the mammalian hormonal balance, resulting, in hyperglycaemia, ketoacidosis and if untreated – in death.
It is a nonsense to say that the cat is not equipped to properly digest raw plant matter. They have been ingesting raw plant material for millions of years – as found, often in great abundance, in the GIT of their prey, particularly small prey, which they ingest whole. I personally have autopsied numerous feral cats (healthy cats, shot by farmers) and more often than not, their stomach contents have included large amounts of plant material. It would be a brave person who would claim that cats do not obtain some benefit from this material. For example, although they have lost the enzymes to convert beta-carotene to vitamin A (clearly they have not required to retain this enzyme system because animal prey is full of vitamin A), that is not to suggest for one moment that they do not obtain some benefit from the anti-oxidant properties of the beta-carotene (and other carotenoids) released from the cytoplasm of the broken down plant cellular material found in the intestines of their prey.
The claim that M. sativa should not be fed to cats on account of its poisonous principle(s) is instantly negated by making a simple observation. Our cat products have always contained Medicago sativa and as a result, this supposedly highly toxic material has been fed to literally thousands of cats. Not one of those cats has suffered as a result – indeed, cat owners are delighted with the improved and ongoing health of the cats that eat our foods.
We put it in there because of the obvious fact that cats have been receiving a benefit from the ingestion of small amounts of raw partly digested vegetable (plant) material [as found in the GIT (undigested in the stomach) of their prey] for millions of years – part of their evolutionary heritage. Clearly, M. sativa is valuable as an unrefined and raw source of plant material, and from the point of view of its nutritional content, one of its most valuable components is its mineral content – most especially its trace mineral content. There are other benefits of course, all well known, so I won’t detail them at this juncture. What I would like to add is that the reason M. sativa has such an excellent mineral content is because of its incredibly deep root system – reaching often, more than forty feet into the sub-soil. This is an area that has not been leached of its mineral content, an area untouched by modern fertilizers. The problem with modern fertilizers such as superphosphate is that they tie up trace minerals, preventing crop plants from taking them up (even if they are present) at sufficient levels to meet the requirements of the eater.
I would be interested to know exactly how many cases of poisoning by Medicago sativa have been reported, how much was fed in these cases, the organ system (or systems) affected and the clinical outcomes in terms of death and/or illness – including all symptoms? If there were deaths or illness, was the toxic principle (or principles) definitely identified? Do they have information as to the levels of the toxic principles in the original ingested material and does this principle vary from region to region, season to season or between different strains of the plant? Do the people making the claim that M. sativa should never be fed to cats have this type of information and is it from a reliable source – for example, is it information as reported by pathology laboratories – or are they working on hearsay and speculation?
I have searched through some authoritative US texts to find information on this ‘problem’ to no avail. The closest any of these texts comes to mentioning it is to say that some grasses cause gastrointestinal irritation – as mentioned in the article which claims that M. sativa should not be fed to cats (as per the link that you sent me - http://felineinstincts.ca/?p=642).
There is no mention of Medicago sativa or Alfalfa or Lucerne under the poisonous plant section in Current Veterinary therapy 14 by Bonagura – the latest edition. This is perhaps the most widely used veterinary text throughout the western world and it certainly does mention a wide range of plants that are poisonous to cats. I have also looked in my copy of Ettinger (not the latest, I must admit – but never the less – the year 2000 edition) and there is no mention of Medicago sativa (or any of its pseudonyms) as a poisonous plant. I have looked at other authoritative cat books such as Sherding and similarly, there is no mention or listing of Lucerne (alfalfa or Medicago sativa) as a poisonous plant. In addition, Dr. Pitcairn, perhaps the most well known and authoritative American veterinarian dealing with holistic matters, specifically recommends alfalfa as a treatment or therapy for cats in his book “Natural health for Dogs and Cats.”
Trust this perspective will be of some assistance to you.
As I have outlined above, I will definitely be most interested to hear of any authoritative information that suggests that M. sativa is dangerous to the health of cats.......
