Very few medicines are licensed for guinea pigs.
Panacur rabbit can be given to guinea pigs - although the dosage needs to be adjusted for their weight Some people advocate using panacur for regular "worming" of guinea pigs. However it is extremely ulikely your guinea pig will have worms and there is only one worm that has been found in UK guineas. If they are exposed regularly to grass that is also frequented by wildlife, dogs, cats, chickens etc then they could, on the off-chance, pick up other types of intestinal parasites such as giardia, eimeria - for which panacur may or may not be effective
It should be stressed that this is a strong drug given to destroy certain types of intestinal parasites. Unless your guinea pig has been clinically diagnosed (by a proper poop culture) with this problem then it is unnecessary to give it for soft poops. Also using it as a "regular worming" routine as advocated by some people is competely unecessary.
Soft poops (not runny ones like full diarrhoea - just soft ill-formed ones) is normally indicative of a disturbance in gut motility (and irregular eating patterns) rather than a gut infection and you need to identify the cause - the mushy poos is just a symptom. Withdrawing veg/grass for a few days and just feeding hay and pellets can normally resolve this. If it persists then some zan-tac (raniti-dine - 2-4mg/kg) to improve gut motility may help.
If there is proper diarrhoea - then a poop culture should be done to identify the cause and the appropriate antibiotics/anti-parasitic prescribed.
Moving onto the pro-bioitics - cats have different digestive systems to guinea pigs as they eat meat whereas guinea pigs are herbivores and hind-gut fermenters. The normal microbes in the gut are therefore different between the two species and a pro-bioitic for cats (or humans) is not suitable for guinea pigs. I therefore would not give this to a guinea pig.
You can get "herbivore" probiotics from the pet shop (eg Vetark) and one - Protexin Fibreplex which can be ordered on-line - is routinely given to guineas with upset tummies as it has the right bugs in it for their guts.
Hope this info helps
