I have two outside areas for Tatum. One, that he doesn't get to stay in all day has a koi pond in it. When ever i put him in that enclosure, he is always attracted to the end with the pond. The water flow from the filter makes a splashing noise into the pond. Is that what he is attracted to, the sound? The other end is heavily planted with all kinds of stuff to eat, which he will graze in, but always wants to get past the barrier and closer to the pond. Any thoughts? BTW, he can't get into the pond, so no worries.
