A cat won't scare him for sure. I kid you not, mine dragged one of our cats in for a quick dunk, the cat soon scrambled out as if a dog was barking below him. It certainly taught him not to atleast dangle his tail down from the Arcadia light he likes to perch himself ontop of. What with a greedy Oscar below staring at a dangling ginger tail, obviously it was too tempting to turn down. Probably an air of caution with that story lol. You'd think my cats wouldnt sit on the light, but they still do, even when the Oscar was still in their.
You will have to keep us updated as s/he grows, as it'll be rapid and they'll change so quickly! Try prawns
Mine went SKIIIITTTSSSS over them.
