A 270-Day Safety Evaluation in Healthy Adult Cats

When selecting a nutritional supplement for daily administration, both palatability and nutritional benefits are important considerations. However, owners may also question whether prolonged daily supplementation could affect their cat’s overall health, particularly renal and hepatic parameters.

To address this question, a 270-day study evaluated the daily administration of different combinations of VFcore lickable nutritional supplement formulations. General health and blood parameters associated with renal and hepatic function were monitored throughout the study.

Study Design and Health Monitoring

The study included six healthy adult cats. Before supplementation began, all cats underwent a physical examination and baseline blood testing. Throughout the 270-day study period, each cat received its regular diet alongside two sachets of VFcore daily.

Different VFcore formulations were randomly paired each day to reflect practical use, in which owners may alternate between formulations or administer more than one formulation.

“Six healthy adult cats received their regular diet supplemented with two sachets of VFcore daily, using varying combinations of formulations, for 270 consecutive days.”

Health assessments were performed at baseline and every 30 days until the end of the study. These assessments included body weight, body condition, food intake, defecation, and blood testing.

Renal monitoring included creatinine, blood urea nitrogen (BUN), and symmetric dimethylarginine (SDMA). Hepatic monitoring included alanine aminotransferase (ALT) and alkaline phosphatase (ALP).

General Health Outcomes After 270 Days

No health problems associated with VFcore administration were observed in any of the six cats during the study period. Overall health remained clinically normal, including body weight, food intake, defecation, and general physical condition.

Renal Parameters: No Evidence of Progressive Deterioration

Renal safety was a key focus of the study. Creatinine, BUN, and SDMA were monitored throughout the 270-day period. No changes indicative of deterioration in renal function associated with daily VFcore administration were observed.

In some cats with SDMA concentrations above the reference interval at baseline, concentrations decreased and returned to within the reference interval by Day 270. This observation alone should not be interpreted as evidence of a renal therapeutic effect.

Overall, these findings support the renal safety of the evaluated supplementation regimen under the conditions of this study.

Serial monitoring of creatinine, BUN, and SDMA over 270 days revealed no trend indicative of sustained deterioration in renal function.

Hepatic Parameters and Other Blood Test Findings

No clinically significant changes were observed in the other monitored health parameters

ALT and ALP activities remained within their reference intervals during the supplementation period through Day 270. Other blood test results likewise showed no clinically significant abnormalities throughout the study.

“Monitoring of ALT and ALP activities revealed no sustained upward trend over the 270-day study period.”

Evidence Supporting Daily Administration

Daily administration of two sachets of VFcore, using varying combinations of formulations, for 270 days was not associated with a sustained pattern of adverse changes in overall health or the monitored renal and hepatic parameters.

These findings provide preliminary evidence supporting the safety and tolerability of daily VFcore supplementation in healthy adult cats under the evaluated conditions. Interpretation should remain limited to the study population of six cats, the administered regimen, and the 270-day observation period.

Alongside palatability and nutritional benefits, VFcore places importance on evaluating the safety of routine supplementation to support informed decisions in everyday feline care.
