Determining the appropriate cage size for your pet rats is crucial for their physical and mental well-being. A spacious cage allows for exercise, exploration, enrichment, and social interaction, which are vital for happy and healthy rats. This calculator helps you estimate the minimum recommended cage dimensions based on the number of rats you have.
General guidelines suggest a minimum of 2 cubic feet of space per rat. This calculator uses these guidelines to provide a starting point. Remember that larger is always better, and additional factors like the rats' activity level and the amount of enrichment you provide should also be considered.
Minimum Recommended Cage Height:
function calculateCageSize() {
var numberOfRats = parseFloat(document.getElementById("numberOfRats").value);
var cageWidth = parseFloat(document.getElementById("cageWidth").value);
var cageDepth = parseFloat(document.getElementById("cageDepth").value);
var minimumCubicFeetPerRat = 2;
var resultElement = document.getElementById("minimumHeight");
var cubicFeetResultElement = document.getElementById("cubicFeetResult");
if (isNaN(numberOfRats) || isNaN(cageWidth) || isNaN(cageDepth) || numberOfRats <= 0 || cageWidth <= 0 || cageDepth <= 0) {
resultElement.textContent = "Please enter valid positive numbers for all fields.";
cubicFeetResultElement.textContent = "";
return;
}
// Calculate total minimum cubic feet needed
var totalMinimumCubicFeet = numberOfRats * minimumCubicFeetPerRat;
// Calculate current base volume (width * depth * 1 inch height) for unit consistency
var baseVolumeInCubicInches = cageWidth * cageDepth * 1;
// Convert cubic feet to cubic inches (1 cubic foot = 1728 cubic inches)
var totalMinimumCubicInches = totalMinimumCubicFeet * 1728;
// Calculate minimum height in inches
var minimumHeightInInches = totalMinimumCubicInches / baseVolumeInCubicInches;
// Display results
resultElement.textContent = minimumHeightInInches.toFixed(2) + " inches";
cubicFeetResultElement.textContent = "Total minimum space required: " + totalMinimumCubicFeet.toFixed(2) + " cubic feet.";
