Solution Steps

Step 1: Determine the Number of Choices for Each Cat

Reginald has 5 different colors to choose from for each cat's collar. Since the choice of color for one cat does not affect the others, each cat has 5 independent choices.

Step 2: Calculate the Total Number of Selections

To find the total number of possible selections of collars for the 3 cats, we use the formula for combinations with repetition, which is given by raising the number of choices to the power of the number of items (cats, in this case). Therefore, the total number of selections is:

\[ 5^3 \]

Step 3: Compute the Result

Calculate \(5^3\):

\[ 5^3 = 5 \times 5 \times 5 = 125 \]

Final Answer

The total number of possible selections of collars for the 3 cats is \(\boxed{125}\).
