Junior Guinea Pig
i feed science selective to my 4 piggies and it is not as expensive as i frst thought i buy 20 kg (i think its this size) sack and iit all gets eaten where as the crunch they picked at so threw half away and had to feed double to make up for what they left so i thnk cost balances out but thats my opinion not actually done any workings out.
