				Abstract 
 
				
				
				Aim: 
				
				To study and compare the age-specific changes in 
				electrocardiographic (ECG) parameters in bipolar limb leads of 
				conscious female native cats of Odisha. 
				
				
				Materials and Methods: 
				
				20 healthy female native cats aged between 4 and 36 months of 
				age were selected for the study. These queens were divided into 
				two groups of 10 animals each. Group 1 constituted the queens 
				aged 4-10 months (before puberty) with a mean weight of 2.28 kg 
				(±0.4 standard error [SE]), and those aged 11-36 months (after 
				puberty) with a mean weight of 3.72 kg (±0.6 SE) were in Group 
				2. The ECG was recorded with a 12-lead standard ECG recorder, 
				Cardiart 108 T-MK VII-BPL (India) in the Leads I, II, and III. 
				
				
				Results: 
				
				The mean heart rates were 160.73 (±7.83) beats/min and 139.09 
				(±2.72) beats/min in the cats aged 4-10 months and 11-36 months, 
				respectively. Significant differences existed among Q- and 
				R-wave amplitudes and duration of QT-interval 
				
				in Lead I. In Lead II, duration of QT and RR intervals, duration 
				of ST-segment and amplitudes of P- and R-waves varied 
				significantly. Significant differences were also observed in the 
				P- and R-wave amplitudes in Lead III. The mean electrical axis 
				was 63.11 (±1.98°) and 50.03 (±4.86°) in the cats aged 4-10 
				months and 11-36 months, respectively. 
				
				
				Conclusion: 
				
				Since the ECG studies on conscious cats are scanty, and the 
				number of native cats being presented in veterinary hospitals 
				and clinics has increased drastically, there is a need to 
				establish the reference values for ECG parameters in conscious 
				native cats so that the cardiovascular abnormalities can be 
				predicted.
