The $\beta$ decay of ${}^{124,126}\mathrm{Ag}$ low- and high-spin isomers into levels in ${}^{124,126}\mathrm{Cd}$ was investigated. We have greatly expanded the decay schemes in these nuclei including the identification of the $0_2^{+}$ and $0_3^{+}$ states among 63 new levels in ${}^{124}\mathrm{Cd}$ and the identification of the $2_2^{+}$ state among 30 new levels in ${}^{126}\mathrm{Cd}$. Several states were identified in ${}^{124}\mathrm{Cd}$, which based on energy are possible multiphonon states. Based on the decay of these states, we show that states in ${}^{124}\mathrm{Cd}$ behave similar to lighter Cd isotopes despite the higher intruder state energies. Our ${}^{124}\mathrm{Cd}$ data support the conclusion that the neutron-rich Cd nuclei are not described well by an anharmonic vibrator interpretation.
