Super Pet Mini Comfort Harness & Leash Discontinued :( Visit and write to http://www.superpetusa.com if you want to convince them to produce this harness again! RattyRat's Review: This is the ultimate harness and leash for your pet rat! It is easy to put on. It fits any, and EVERY sized rat there is, even youngsters. It is almost impossible for them to wiggle out of. It is very small, and hardly noticeable to your rats when they wear it. (be sure to put the loop that tightens on them as they pull, around their body, not their neck.) No other harness works as well as this one. Every rat we've tried this harness on, accepted it immediately.
