I would think any hardware store should have that tubing.
I know Home Depot/Lowes have the huge rolls of vinyl tubing that you can cut to length.
Or get a length of PVC
, put a barb fitting on both ends and you can cut python tubing where you want and extend it(cats have more trouble biting through pvc
). I have two lengths with a union in the middle so it breaks down easy but is still waterproof. That would be the cheapest route IMO
and you can always use a piece of PVC
around the house at some point.
