Pros, cons & Future potential


It is possible to train persons for performing these techniques without sacrifying animals. It is a good start for people that have no experience at all and also nice to use in a practical where students that do not intend to ever work with rats (or other lab animals) are present.


The model has only a limited value since there are quite a lot of differences with real rat tails and the flexibility of the rat is also very limited making it impossible to use certain gavage tubes. It is also quite expensive (certainly the spare tails) and not all tails are from equal quality.


I do not have it yet, but I am thinking to possibly switch to the curvet rat, a similar model that can also be used to learn subcutaneous injections.
