She's a Tiger made her racecourse debut in a maiden race over five furlongs at the Alameda County Fairgrounds in Pleasanton, California. The race proved to be little more than a workout for the filly, who started at odds of 1/5 and won by nine lengths. Three weeks later the filly appeared on the synthetic Cushion Track at Hollywood Park Racetrack and started 3/5 favourite for the Landaluce Stakes over six furlongs. Ridden as on her debut by Frank Alvarado she took the lead soon after the start, went clear of her rivals in the straight and held off the challenge of E Equalsmcsquared to win by three quarters of a length. In the following month, She's a Tiger was moved up in class and distance for the Grade IISorrento Stakes on the Polytrack surface at Del Mar Racetrack. She led the field in the straight and fought back after being headed, but was beaten half a length by the Canadian-bred filly Concave. On September 1, over the same course and distance, She's a Tiger and Concave met again in the Del Mar Debutante Stakes, a Grade I event which also attracted the highly regarded fillies Awesome Baby and Fascinating. Gary Stevens rode the filly for the first time and disputed the lead with Awesome Baby from the start, before opening up a two and a half length advantage in the straight. She was challenged in the closing stages but "ran on gamely under pressure" to win by half a length from Fascinating. After the race, her trainer Jeff Bonde commented "She got stronger, and when we added she got more focused. She was very professional in the paddock. A lot of Tale of the Cats can get a little hot, but she's got such great mentality and I'm really pleased with her". The filly then moved to racing on dirt when she contested the Grade I Chandelier Stakes over eight and a half furlongs at Santa Anita Park on September 28. She's a Tiger took the lead on the backstretch and took a clear lead but was worn down by the Rosie Napravnik-ridden Secret Compass in the closing stages and beaten a head, with Fascinating finishing strongly to take third place. She's a Tiger ended her first season in the Breeders' Cup Juvenile Fillies at Santa Anita in which she was again ridden by Stevens. She started at odds of 4/1, level with the Spinaway Stakes winner Sweet Reason and behind the Frizette Stakes winner Artemis Agrotera, who was favored at 7/2. She took an early lead and went four clear of her rivals on the final turn. In the straight the 40/1 outsider Rio Antonia emerged as the only serious challenger and the two fillies were level with fifty yards to run when She's a Tiger edged away from the inside rail and bumped her rival. She's a Tiger crossed the line a nose ahead of Rio Antonia, but after an inquiry by the racecourse stewards, she was disqualified for causing interference and demoted to second. Bonde described the result of the inquiry as "just heartbreaking". In January 2014, She's a Tiger was named Champion Two-Year-Old Filly at the Eclipse Awards, taking 212 of the 249 votes.
