Well my rats have been having a time breathing lately, the allergens around here are driving us all crazy. But seeing my ratties sneeze repeatedly forced me into action. I have purchased a new Kenmore Progressive 335 air Purifier. WOW!! What a difference it has made..We all are breathing better a not a sound from the fluffs. It really does pay to invest in one of these for yourself and the rats, mice, hedgies, guinea pigs, etc. etc.
On a side note, the rats are completely obsessed with mini Milkbones..they are even turning away the yogies..I still cook them a dinner every night, but nothing takes precedence over Milkbones.
