I thought about having a net over the pond but also was worried that as they are let out at night in their cat proofed garden they would get caught in it so haven't got a net over. It is only a smallish pond ie 3ft x 3ft and there is easy exit points and low edges with a cat walking plank across the middle.
Garf has fallen in once and Marl has actually jumped in by accident while playing with a toy (ooops) They both got backsides wet but got out easily.
They both drink from it as they like the water with no chorine in it and Garf always watches the fishies for ages. Never caught one thank god.
When they were littleuns, i was always with them outside in the garden.
My boys at the bridge Rio and Gizzy also were here since we have had the pond and Gizzy too no interest at all in it and never accidently went in. Rio on the other hand loved fishy watching and did catch one fish but i saved it and he (the fish) (preseume it was a he lol ) is fine and as big as the others
Rio never accidently went in at all.
