In this study, it was aimed to evaluate the effectiveness of intratesticularly administered lidocaine and bupivacaine in castration in cats. 20 cats were divided into two groups regardless of breed and age. 80 microgram/kg medetomidine injection was administered for sedation. 4 mg/kg lidocaine or 1 mg/kg bupivacaine were injected intratesticularly in lidocaine and bupivacaine groups respectively. Castration was performed with routine methods. The reactions of the animals to the incision and the extraction of the funiculus spermaticus were recorded. After the operation, the animals were awakened by atipamezole. The pulse rate, respiratory rate and pain scores were evaluated for 6 hours at half-hour intervals. UNESP-Botucatu cat pain scale, Grimace cat pain scale and Glasgow cat pain scale were used to evaluate pain scores. A statistically significant difference was found between the groups in Grimace and Glasgow pain scores at the 150th min. and 180th min. postoperative evaluations (p<0.05). A statistically significant difference was found between the groups in Botucatu pain score at the 60th, 90th, 150th, 180th, 300th and 330th min. (p<0.05). No statistically significant difference was found in the pulse and respiration values ​​(p>0.05). As a result, it was determined that bupivacaine should be preferred to lidocaine for long-lasting surgical procedures and postoperative analgesia due to its long duration of action.
