Well my pets are kinda children in they need me for care so here's mine. My cats enjoy lounging on top of my 50g tanks hoods all the time to get the best view of the room and drink water from the filter return (even though they have their own fresh water bowl). I can't for the life of me get them to stop. Just next to my 50g was my 20g tank which they took to using that day as I cut off their usual route to the tank. I was getting water into my bucket in the bathroom for a pwc
and had left the lid open on the 50g. All of a sudden I hear a jump, then a crash landing followed by the sound of sliding plastic and finally a splash. My cat hadn't seen the lid up and tried jumping from the 20g lid to the 50g. I assume she freaked out seeing water where there was supposed to be her landing strip and fell back on the hood of the 20, causing it to fall into the tank. Thankfully my 2 yellow bullhead were ok but the hood and light were toast. Now I have the bullhead in a spare 55 I had with no lids. Stupid cat hasn't learned it's lesson and still jumps onto the 50g hoods. Maybe I should completely take the hood off and hope it tries to jump again only to go swimming. That would teach it.
