That really sux rottie, but what makes you think you'll have any more time for a guinea pig then you had for Thelmer? Just curious. Also your parents will have to pay for vet for the guiea pig as well. Guiean pigs also have A totally different diet plan then Rabbits, hope you know that. Guinea pigs are also more messy and require more space and also company. Also what makes you think that your whole family is going to liek a guinea pig? this confuses me.
