My lease says 'no pets' but also charges a $45/month 'pet fee', what does this mean?

I'm looking at a lease that has a 'no pets' clause in section 6 but section 11 has a $45/month 'pet fee' and a $300 'pet deposit.' My agent says the 'no pets' clause means 'no pets without approval' and I'd need to get a pet addendum. But then what does the fee in section 11 mean if pets aren't allowed? This feels contradictory.
