采用两种放射性核素血液标签（cr -51红细胞和i -125白蛋白）和重量法，研究了猫母蚤猫头蚤（Ctenocephalides felis, Bouche’）在禁闭饲养箱中饲养3 h时的耗血量。使用双放射性核素系统测定，每100只雌性跳蚤在3小时内平均消耗0.110毫升（±0.026毫升）血液。单个cr -51红细胞标签高估了血液消耗11.3%，单个i -125白蛋白标签低估了血液消耗6.4%。与双放射性核素值相比，重量法低估血耗72.2%。研究人员将猫关在代谢笼中，限制其梳理毛发，并对不受限制的雌性跳蚤的血液消耗情况进行了调查。这些调查是使用单个cr -51红细胞标签进行的，所获得的数据被纠正以补偿使用单个红细胞标签。雌性猫蚤平均每天消耗13.6 μ l（±2.7 μ l）的血液，相当于其体重的15.15倍。在另一项研究中，直接暴露于40千赫的超声波并没有减少跳蚤的血液消耗。
The volume of blood consumed by actively reproducing female cat fleas, Ctenocephalides felis (Bouche'), while feeding in confinement feeding chambers on cats for 3 h, was investigated using two radionuclide blood tags (Cr-51-erythrocyte and I-125-albumin) and the gravimetric method. Female fleas consumed an average of 0.110 ml (+/- 0.026 ml) of blood per 100 females in 3 h as determined using the dual radionuclide system. The single Cr-51-erythrocyte tag overestimated blood consumption by 11.3% and the single I-125-albumin tag underestimated blood consumption by 6.4%. The gravimetric method underestimated blood consumption by 72.2% compared with the dual radionuclide value. Investigations of blood consumption of nonconfined female fleas were conducted with cats housed in metabolic cages and restricted from grooming. These investigations were conducted using the single Cr-51-erythrocyte tag, and the data obtained were corrected to compensate for using a single erythrocyte tag. Female cat fleas consumed an average of 13.6-mu-l (+/- 2.7-mu-l) of blood per day, which was equivalent to 15.15 times their body weight. In an additional study, direct exposure to 40 kHz ultrasound did not reduce blood consumption by the fleas.
