Rats weight decreased from 3.84 % to 18.59 % (P&lt;0.05), respiration rate from 18.65 % to 24.59 % (P&lt;0.05) when rats were housed in metabolic cages.

We did not observe significant changes of triglycerides concentration, red blood cells count and total protein between all rats. The positive moderate correlation of rat housing in a metabolic cage was between K blood and K urine, P blood and P urine, Na blood and K blood, between Na urine and P urine and significant negative moderate correlation was determined between K urine and P urine. These present study findings indicate that metabolism cage housing significantly affects rat’s physiological parameters and potentially may influence animal health and wellbeing.</p></abstract>
