The fur on the tails of Grimalkin eggs are always standing on end. Loud hissing and erratic tail movements will follow any attempt to make physical contact with one of them.
About the Grimalkin Creature
Grimalkin are known to produce allergens that will commonly cause intense allergic reactions in humans and other creatures alike. Itchiness, coughing, sneezing, and other uncomfortable symptoms have been reported by those previously unaffected by feline allergens and it is for this reason that Grimalkin are considered unsuitable as indoor pets.
