Background: Trichobezoars represent a frequent digestive issue in cats, often resulting from excessive hair ingestion during grooming. This study evaluated the effects of keratinase-psyllium husk as a feed additive to prevent trichobezoar formation. 
 
Methods: The trial included 20 healthy adult cats, randomly divided into three groups: KP-L (low-dose keratinase-psyllium husk), KP-H (high-dose keratinase-psyllium husk) and Control (standard diet without additives). Each group received their respective diet for pre-trial 3 days and a formal trial 14 days. Parameters analyzed included keratin degradation, fecal trichobezoar excretion and blood indicators to assess overall health status. 
 
Result: The findings demonstrated that cats in the KP-H group exhibited significantly higher keratin degradation and increased fecal trichobezoar excretion compared to the KP-L and Control groups. Both KP-L and KP-H groups showed improved hair elimination, though the effects were dose-dependent. No adverse effects on hematological or biochemical parameters were observed, indicating the safety of the additive. The study suggests that dietary supplementation with keratinase-psyllium husk effectively enhances hair degradation and trichobezoar excretion in cats, with higher doses showing greater efficacy. This additive presents a promising preventive approach for managing hairball formation in feline diets.

<div style="text-align:justify">Background: To determine the prevalence of indigestible foreign bodies in rumen-reticulum of cattle. Identify the types and the common diseases associated with their occurrence. 289 cattle were examined at Batna (Algeria) municipal abattoir. 
Methods: About 289 cattle were examined immediately after slaughtering to determine the presence or absence of the foreign bodies in their rumen-reticulum and different lesions were recorded. 
Result: From total of 289 cattle examined 151 (52.24%) were found positive for various types of foreign bodies in their rumen and/or reticulum. From each 56 (19.37%) and 95 (52.24%) were positive for vulnerable bodies and non-vulnerable foreign bodies respectively. The types of foreign bodies detected were: wire segments, needles, nails, hair clips, coins, corks, ropes, cloth, pebbles, sand, glass pieces, trichobezoar, plastic bags. The plastics were the most common found in 61 (23.92%) males and 34 (79.06%) females. The most common lesions in rumen of cattle with Foreign bodies were traumatic reticuloperitonitis, perirecticular abscess, esophageal obstruction, non penetrating reticulum and/or ruminal foreign bodies were respectively 3.79%, 12.65%, 1.26% and 82.27%. The study revealed that the plastics in rumen my play an important role in the pathologenesis of cattle.</div>
