Big scam
Unfortunately, I thought this pack was 30 litres, but apparently it only corresponds to 30 litres of regular cat litter. There’s no Czech translation on the packaging, and in a foreign language it just says the number 30 in the context that they’ve been on the market for 30 years. This two-colour pack is probably only about 10 litres, really. Misleading advertising, no Czech instructions, and not exactly cheap either.
