Check to see if your grocery store sells wheat grass in the organics section! It’s a much better deal too, costs less and there is more grass that is always healthy and fresh. Sorry still bad for the environment I don’t have a solution there, but the plastic is less substantial than the pet store ones at least.

Or I guess you could buy a ton of dollar store mini planters to grow in and start rotating them for kitty and leave them outside otherwise. That’s a lot to feed the grass habit lol
