The studies behind our cat urinary health guides
Editorial proofreading complete · qualified veterinary review pending.
All 41 numbered sources are available below.
Want to check a finding for yourself? This index links the original publications behind our evidence review and owner guides. A paper’s title is the authors’ title; wording such as “risk reduction” does not by itself establish fewer clinical blockages. Read the population and outcome before applying a finding.
The inherited public bibliography contains references 1–40: 34 primary empirical papers and six reviews. The local working edition adds the 2025 clinical consensus guideline as reference 41. Reviews overlap the studies they discuss, and publications are not necessarily independent experiments. These are not 41 new MSRA trials.
How to read the access notes
“Relevant original full-text sections checked” means the audit examined pertinent methods, results or disclosures, rather than completing a formal assessment of the whole paper. “Indexed original sections checked” means original text was visible through an index while direct retrieval was limited. “Original abstract checked” has a narrower basis. A free full-text link is a reading route, not proof that the full paper was appraised. Notes describe MSRA’s recorded access, not the availability of a paper everywhere.
No complete independent risk-of-bias appraisal or qualified clinical review of this MSRA collection has been completed. The technical review explains the missing historical methods and inclusion registries.

Corrections and questions
If you notice a source mismatch, tell MSRA which guide, section and publication you mean. MSRA cannot assess urgent symptoms by a research query. A cat repeatedly straining with little or no urine needs immediate veterinary contact; do not wait for a reply. PDSA emergency guidance
