I agree with all these products they do ..do the job....but I asked my hairdresser the best way to stop static she told me to do the last brush with 'a little bit ' of spray on a VENT brush (human) I tried this with my brush on my girls and it works great!
I get terrible static in my hair and I rub a 'Bounce' sheet (tumble dry fabric softner things) over my hair..works a treat! smells nice too :D (think Storm would be verrrrry miffed if I did it to him though and made him all girly,fox poo being his equivalent of Old Spice :rolleyes:!)
When my hair starts pointing at the ceiling I just dampen my hands slightly and run them lightly (barely touching) over my head. Works every time for me but so far my ears haven't started up so I don't know about your cavies. :-D
