For many of us, getting our hands dirty in the OR is infinitely preferable to spreadsheets, graphs and statistics.

Neonatal l kittens (0-2 weeks old) are our most vulnerable and fragile patients. Increasingly, shelters are able to help and save these kittens.

Historically, canine demodicosis has been a difficult and frustrating condition to treat.

I was asked recently what would be considered an acceptable complication rate for a high-quality-high-volume spay and neuter (HQHVSN) clinic.

It’s common practice to apply corn syrup to the oral mucosa of kittens after pediatric surgery.

Famciclovir (Famvir) has been around for a while as a treatment for feline herpesvirus infection. Until now, though, we haven’t really known how much to use, or how often. A new study has some answers. First, though – when should we consider using Famvir? It’s not always straightforward. If there is severe stress and overcrowding,
