Answer:
False
Step-by-step explanation:
Pertelote says is stating that she agrees with Cato: "It was the philosopher, Cato, who said 'think nothing of dreams'. So, do stop going on about your piffling little daydream and take a laxative".
To which Chanticleer responds: "Madam, I'm sure Cato is very wise, but there are many writers much wiser than him who agree that dreams are very serious portents".
Therefore, it's clear that Chanticleer does not agree with Pertelote nor Cato.
