do u give suppliment?

[malabui]

I have Never given any of my gerbils any vitimin suppliment. They don't seem to need it.
Just make sure that they have a balanced diet, like giveing some fruit/veg as well as their dry gerbil mix

Supplements are useful in 3 cases
1) a pregnant or nursing gerbil you are concerned about (but a balanced diet is much better)
2) a weak gerbil (runt or elderly) to give them a boost, especially if they are not eating well
3) a gerbil who's been sick and/or on antibiotics, in which case a course of probiotics may be useful. The ones I use also contain multivitamins.

I recommend Vetark products www.noahs-cupboard.co.uk/index.asp

They are expensive but UK P&P is included in the price.
Generally a balanced diet is much better than supplements though.

my gerbils have a small salt wheel that they'll nibble on every now and then. But, that's about it.
