^a The difference between type I and II lactones is the position of the carbonyl group [30]
^b Linear retention index relative to n-alkanes on a DB-5ms column
^c The same letters in the second column of this table indicates these compounds are diastereoisomers: stereoisomers with one or more differing stereocenters resulting in different molecules that are not mirror images and not superimposable
^d These compounds were only prepared in small amounts and used as standards in the GC-MS analysis, but were not used in bioassays with cats
^e Liquid at room temperature
