GIANT-SIZE Vampire Hirudo Verbana European Bloodsucking Leech (aka the Hungarian Leech). Sold as: Leeches as Pets. Not Suitable for Leech Therapy. The Giant pet leeches is a beautifully colored Hirudo Verbana Medicinalis Blood sucker leech of the European variety. This is the original type of leech that was used in Leech Therapy throughout the whole of Europe. Hirudo Verbana is also believed to be the basis of Bram Stoker's Dracula novel which portrays a human being - a count, who really possessed leech-like behavior and was himself believed to be a leech disguised in human form. Some species of this Hirudo variety leech become very large in size and are preferred kept as leech pets by some people because they are easy to take care of. The Giant leech pets feed on blood of humans and mammals and are at least 1 year of age. Those leeches can go up to a year without feeding as well and when they start moving, they are slower to move about, but much more robust than their smaller Verbana Hungarian leech or Hiurod Medicinalis Medicinal leech counterparts. The giant pet leeches can be fed every 3 to 6 months on your house pet or on your own self, such as on your arm or back of the neck. These leeches will expand to quite a Huge size when fed and full of blood. They suck on the blood fast and very confidently. This pet leech is an experienced bloodsucker and is not hesitant in its biting the chosen area where you've placed it. You can also place it on a dog, cat, sheep, cow or horse to feed from. As it doesn't require that much upkeep and feeding, it is considered the perfect aquatic pet for some who have decided to try something different. The giant hirudo Verbana are intelligent creatures and very lively and fun to maintain and look after. They have a mind of their own and a personality as well. If you are looking for another leech with a personality, the buffalo leech is another alternative to tray and raise as well, although they are much more difficult to maintain and care for. If you purchase two pet leeches of this giant size and you keep them together, they will eventually mate in spring and one might become pregnant and give birth to a leech cocoon full of baby leeches.
