Timeline of the experimental design. Weanling female rats were exposed to soiled cat litter for 10 consecutive days from postnatal day (PND) 21‐30 followed by daily monitoring of vaginal cytology from PND 28‐42 to determine puberty onset and oestrous cyclicity. Rats were tested on the elevated plus maze (EPM) and social interaction was assessed as indicated on the timeline to determine anxiety‐like behaviour. The experiment was terminated on PND 44 and brains were collected for gene expression studies
