If Hermione ever invited Krum and his Kneazle to stay in the house, he would be doomed. It was common knowledge that Kneazles were very possessive and protective of their mates and offspring. A Kneazle pair would never be separable until the birth of baby Kneazles. Kneazles bred quicker and more frequently than other pets. The litter size was often small so they were quite rare.
