Can't believe I didn't review them sooner. I took my two cats there from 2006 until 2010. One of my cats was diagnosed with CRF (Chronic Renal Failure) in 2008 and Drs Beaudin and Brunet put her on a regime that has kept her mostly stable. They are definitely pricey, however. Here where I am in France currently, prices for certain CRF monitoring tests are half of what they cost at Chats Montreal - and that's with the currency exchange factored in! So be prepared to drop some cash or negotiate with staff. Nevertheless, I do believe my cats received solid treatment and care, especially in the case of my CRF kitty, whose disease was caught early (only because I mentioned that she drank a lot of water). Dre Louise Beaudin in particularly is very caring and explains everything. In sum - an excellent, if pricey, feline clinic.
