Drinking a lot more than usual in rabbits
What this sign can mean and when to act, from House Rabbit Society and RWAF guidance. This is general information, not a diagnosis.
What you noticed is worth a vet's eyes soon. Rabbits are good at hiding when something is wrong, so it's best to have your exotic vet take a look before anything has a chance to progress. Book a routine appointment in the next day or two, and call sooner if anything gets worse.
What it can mean
Drinking a lot more than usual can be associated with kidney disease or reduced kidney function, a urinary tract infection, or in rarer cases a hormonal condition. It can also be a normal response to a drier diet or warmer weather, but if nothing obvious has changed, your exotic vet can run a simple urine and blood test to rule out an underlying issue.
