A new Dartmouth study finds that cat owners donate slightly more than dog owners, and also donate more often and more diversely. However, people without pets donate the most. The findings are published in the journal Anthrozoӧs.

About The Study: From 2020 to 2025, prior authorization for glucagon-like peptide-1 receptor agonists (GLP-1RAs) became near universal and out-of-pocket costs rose substantially in 2025, as plans increasingly required coinsurance. Although the rise in prior authorization may reflect efforts to curtail off-label GLP-1RA use, recent increases in out-of-pocket costs likely resulted from broader shifts to coinsurance affecting many high-cost drugs.

Hospitals with the widest difference between the cost of their services and what they charge patients and their insurance carriers are mostly for-profit, investor owned and located in large metropolitan areas. They also have significantly worse patient outcomes compared with lower-cost hospitals.
