Some plants naturally smell like this due to their higher nitrogen and sulfur content, sometimes it's due to the concentration of the nutrients you're using.

What's the strain? Most strains with the cat urine smell hit hard and rough, but contain a fair amount of THC versus CBD and thus gets you fairly high, and the THC-V content makes it kick in FAST and HARD, but it mellows out fast to the THC buzz. This is a common trait in Asian strains.
