Hi Mart I have read through your thread with interest, may I make a suggestion re wood shavings its NOT a criticism so PLEASE dont take offence , and you dont have to take the advice either if you dont want to.
Wood shavings , and other woodtype stuff, is not recommended for guinea pigs, and yes, I know the pet shops sell it for the purpose. But the reason being that wood shavings contain natural and treatment chemicals - you can smell them its quite nice.However wood shavings and pig urine are not a good combination, the pigs have short legs and their little noses are therefore quite close to the vapour which is created. They cant escape it, some pigs on shavings become quite chesty as a result. Secondly as they are not particular about where they wee, they will be running backwards and forwards through the wet shavings and can therefore become prone to urine burns on their feet.I suggest you try a good wodge of newspaper to line the base of the cage with a covering of hay - not straw as this does not soak up the urine, often causes eye injuries and has no food value for the animal either. You will save yourself a lot of money , your pig will be happy , and I think the skin on his feet will start to improve. And consider the advice given about taking him to see a real pig specialist Good Luck.
