Learn how to replace the straw in your Munchkin Cool Cat cup. Simple steps to fix a toddler cup straw and keep it working like new.
Quick answer
Replacing the straw in a Cool Cat cup takes about a minute. You just need the official Munchkin replacement straw and a clean workspace.
Why use the official replacement straw
Munchkin's Replacement Straw for Cool Cat Cups is made to fit the double-walled design. A generic straw may be too short or too long, which can cause leaks or make the cup hard to drink from.
The official straw is BPA-free and designed to match the valve in the lid. Using it keeps the cup working as intended and avoids frustration.
When to replace the straw
Replace the straw if it shows signs of wear like cracks, tears, or if it no longer stays in place. Toddlers can be tough on straws, so check every few weeks for damage.
If the cup leaks around the lid or the straw slips out, that is another sign it is time for a new straw.
Steps to replace the straw
- Remove the old straw: Pull the old straw straight out from the lid. If it is stuck, twist gently while pulling. Do not use tools that could scratch the plastic. Do not yank hard; you might damage the lid valve.
- Check the lid opening: Look inside the lid hole for any debris or old straw pieces. Rinse with warm water if needed. A clean opening helps the new straw seat properly. A blocked opening can cause the new straw to not seal.
- Insert the new straw: Push the new straw into the lid hole until it stops. It should feel snug but not require force. If it slides in easily, you may have the wrong straw. If the straw does not sit flush, it may not be the correct replacement.
- Test the seal: Fill the cup with water, close the lid, and turn it upside down over a sink. A few drops are normal, but a steady drip means the straw is not sealed. A quick leak test saves a wet shirt later.
