LOL at the cat box odor solution. I think your cats would revolt much earlier than 8 weeks though
You're still early in the process so you have time to figure this filter thing out. My DIY efforts yielded mixed results: The Red Greenery rubbermaid filter worked well for my first grow, however it was big, unwieldy and the carbon bed tended to shift around. That made areas thinner than others, using it up more quickly. The standard "attach ball of carbon wrapped in nylon to 120mm fan" sort of worked, but the airflow was reduced to almost nothing, and the carbon would always shift due to gravity and vibration.
My suggestion is get yourself the smallest can-style filter you can buy, and jimmy rig some 120mm ducting to push air into it. Then you can hide it wherever you want, and get rid of 100% of the smell. The peace of mind you get with good odor control is worth it, trust me.
