Yup, cats! They once attacked me and stole my chicken roll, so I'm kinda scared of them anyway

I think I'll go for the Repti Glo again, it seems to be the easier choice since I wont have to buy the voltage converter and things.. I have a screen but it isn't mesh, the spaces are around 1/2 inch wide so I think the 5 would be appropriate right?
Thanks guys!
