That was an interesting chuckle to watch. Thanks for the research.

I think my cats AND my son would look at me like I'm crazy if I started using cat litter on my builds, but it is certainly an interesting thought.

I will be doing a sizable layout in the future, I`ve gone for calcium sand from charterhouse aquatics 5kg and 10kg bags are just over £6-12 a bag

Good video. It hadn't occurred to me to try cat litter as ballast, but now I know not to try it. Also, I've heard that Chinchilla dust can be used for ballast but have not tried it. Not sure whether that would result in any cost savings.
