I have been using Oxbow for a while now and have recently been directed to Vetafarm which is an Australian product. You can view film clips of how to care for you critters on youtube. I have been buying thier Fescue hay/guinea pig pellets and also have some crittacare for emeregencies. Dougal loves the hay and pellets but his all time favourite is the Oxbow Orchard grass! Something I didn't realise is that when Oxbow products are imported they are irradiated. So I need to find out if that takes out the goodness from the pellets and hay/grasses.
i have used Vetafarm,when i used it i noticed a huge difference, my pigs became chubby and lacked energy and weren't as vibrant looking, i also tried the rat pellets with my ratties once and they were full of colours and artificial flavours, they looked and smelt like fluro popcorn.
\i switched straight to Oxbow and have been happy ever since, i hope vetafarm has improved since i used it last year
