If you are the proud owner of a mischief of rats, this really is the best veterinary hospital you could hope for. Very conveniently located too, and not a long walk from Vendôme Metro if that is a concern.
The reception staff are some of the downright friendliest people I ever had the pleasure of meeting. The veterinarians too are wonderful people.
It can be a little expensive to open a file for each individual small, short-lived animal. The money is well spent, however, for the level of care and kindness your little friends will receive. Great place that I highly endorse.
Edit: After a number of additional visits, for assorted reasons, I will reconfirm everything listed above as still being true since my first review. You and your pet will want for nothing while here.
The facility also boasts a small store with modestly priced goods that every small rodent owner needs at some point. This is one of the best places to go if you are a rat person, though I am sure they serve other types of animals just as wonderfully.
