So I've been dry for a couple years now and really want to get an aquarium going again. One problem we had with the last one was that our cat would want to jump on to the cover glass and sit there. We were always scared it would break, and so kept that tank (a 10G) in a room we could close off when we weren't there to keep an eye on things. But we never got to enjoy the aquarium very much because of that.

Not using a cover glass isnt an option: because of where we are, in the winter especially I will loose 20% of my water inside of a week to evaporation! And no, getting rid of the cat is not an option. I'd like to do the proverbial ADA 60P with their cover-glass/metal clips but I feel sure that if the cover glass doesn't break from him stepping on it, the metal clips will stress/crack the top edges of the aquarium itself with equally disastrous results.

Any thoughts?

Can you situate the tank so there's no good approach for the cat to get to the top of the tank? I have had a cat or two that maybe would maybe jump from the floor to the top of the tank if they were *really* determined, but most wouldn't bother unless there was a better place to launch from. If you had the tank on a stand with no ledge and no nearby chairs, counters, etc. that might be enough of a deterrent.

An acrylic top would probably be less likely to break, though that wouldn't help with stress on the tank itself.

Keep in mind that water is around 4-5 pounds/gallon. So a 10 gallon tank is at least 40-50 pounds when filled (not including equipment, substrate, fish, light, heater, etc.).

My question, is how heavy is your cat????? If it's heavy enough for you to be scared about it breaking the glass, then that sounds like an incredibly heavy cat...unless its name is Garfield and either you or your partner's name is Jon.

Back in the day (2003ish), I had a 10 gallon that I covered with a piece of 1/4" scrap acrylic that I had and cut to size. My cat would routinely sit on that with out problem. She'd even sit with her back end on top of the tank and her front paws in front of it, twisted around to look in the tank. It was quite comical.

Another approach would be to arrange it with lights, filter, etc so that there isn't much of a remaining flat surface for the cat to perch on.

Water is ~8.3 lbs/gallon, but that doesn't mean that the tank can withstand the repeated impact of the cat jumping on and off the lid. I mean, maybe it could, but you wouldn't want to be wrong and wreck your fancy rimless tank.

I have a 6 pound cat and a 17+ pound cat and thank goodness only the tiny one occasionally stands on my quarantine tank. The lid is black plastic and the tank is rimmed - I really don't think she can do any damage, but I'd be a bit nervous if it was my big boy. (FWIW he's not fat, just a giant. He has normal proportions, but is just extra tall and long - it's a bit strange.)

Thanks everyone for the thoughts. No hes not particularly heavy. On the light side for cats actually at <10lb. I just dont know what the tolerances are for this stuff. :)

The acrylic top is a good idea, but I'm still thinking that those tiny ADA metal clips are still going to be "pressure points" on the top edges of the aquarium proper...

Oops, that's my bad. Elle's got the right pounds/gallon for water. Please blame sleepy ichthyogeek for the 4-5 pound metric.

For a <10 pound cat, I don't think I'd worry too much about it. Then again, I don't have a cat...but you could also email ADA and ask "hey, what weight can the tank glass hold? I have a cat."

Maybe you could negatively associate the tank? Something like a spray bottle whenever the cat tries to jump on the tank lid?

leave the cover off , pick up cat, dip its feet in the tank, it wont jump on there after that unless you have one of those broken cats born without the hydrophobic gene.. <a href="http://www.plantedtank.net/forums/images/smilie/icon_smile.gif" border="0" alt="" title="Smile" >:)</a>
This could definitely be an effective deterrent.

We just got a 150G livestock tank setup in our basement. Our one cat who has to climb on literally everything decided to climb around on the very narrow slippery edge of the tank. One day I'm sitting at the computer and hear a loud splash. Sure enough he slipped and his whole hind end fell in the tank. Hasn't climbed back up there since.

He still thinks the sump is one of those fancy circulating water dishes just for him. But I can live with that LOL.

I reached out to AngleFins with this question. She was pretty clear: the little ADA metal clips are not going to support any weight to speak of. Her suggestion was a cover glass which extends over the edges, which would be very doable. I just wonder if that will create a new concern: condensation on the bottom of the cover glass wicking out and down the outside of the aquarium.

This cat is not making things easy for me. lol

You will probably need a thick smear of silicon on the lid where it will rest on the tank edges to soak up any irregularity/grit that may stray between them, you could also run a bead about half inch away from the edges to ensure most condensation will drip before reaching the edges.

Soooooo I would try training him to not think of it as a surface to sit on so he would just stop trying completely.

I'd fill it up with water - and leave the top off and let him learn that when he jumps on it he lands in water and he'd only need to do that once or twice to likely cure his desire to see it as a perch.

OK.. my thought.


First getting glass from a glass place

is "usually" no more costly than buying a lid.


Second get tempered glass because 1)stronger and 2) won't break into a dozen knives..


If rimless get it cut and tempered to the exact size of the tank plue a wee bit little larger so you can deal with it without
attaching a handle



Third attach one of the Marineland handles to it.if you don't do 2


Forth, just run a bead of silicone around the INSIDE area forming a lip and "sort of"

tall as you can.

Allow to cure.

Actually if the glass guy has small square glass rods all the better..glue that on in a few spots or entire
rim




Use a small spot or stick on feet to give it breathing room

Can do the same in acrylic but make sure you get cell cast so it won't warp w/ humidity..

This just happens to be a very timely thread for me as I will be picking up a new kitten in about a week. She'll be on the larger side as she matures and may get up to 13-15 lbs. It's been over 12 years since I've had cats and back then I had only one tank which was rather tall (26g bow) and the cats never tried to jump on it - no easy platform nearby from which to start.

This time, I have 4 standard Aqueon tanks with glass lids on stands, and one small Spec V on my kitchen counter. Not all of my lids are as snug as they could be as I really just haven't been able to cut through that plastic strip on the back. May have to elicit some help there to shore things up a bit more.

My plan is training, training, and more training. So I'd like to ask all of the cat owners out there, what are my odds of success with training? I also like the suggestion of the aluminum foil as a training aid - may try that if needed, thanks.

once mine has investigated something new a couple of times it ignores it unless there is a change in position or additions add a new smell to rekindle curiosity , the exception is if there a reason to be there such as being the warmest flat surface to sleep on or just being the highest easily accessible spot to watch its humans from so maybe providing a warmer higher spot to lurk on than the tank lid would help in addition to the aversion therapy ?

I dissuaded my 16lb girl from the top of my tank with double sided tape. I put a piece of plexiglass covered in thin double sided tape on top of the tank. The first time she jumped up, she stepped right on the tape, freaked the [email protected]# out, and never did it again.

Put a cucumber on top of your tank. Apparently (from youtube videos so I have no scientific proof of this) cats hate cucumbers.
