cats are only good for target practice

Secretly? You really should've put them out of the way and securely imo. And anyway was your cat a ninja? Did it or the goldfish make any noise? Seriously!

that's your fault for carelessly cleaning. you should've never cleaned.

if you have a cat..why would you leave fish anywhere you know the cat can get to them? their blood is on your hands >=p

Oh, this is great. The comments are funnier are than the OP.

get new fish and kill the cat problem solved

cats ftw xD

my cat did the same when I was filling my iguanas water I sat on the tail a day later on the floor

well only way to replace the fish is put the cat in the tank

OP - There was absolutely NO need for you to remove the fish from the tank to "clean" it. The only cleaning you need to do to a tank is aglae removal from the glass, and gravel syphoning to remove uneaten food and solid waste. You should change 25-50 % of the water in any fish tank PER WEEK. The fish do not need to be removed for this process at all. @ Love me electric - YOU are the cockroach. Bettas can SURVIVE ( NOT live, there is a difference ) in small bodies of water in the wild , and you know something else? Thousands of them die in those muddy footprints. Which begs the question as to why idiots with your frame of mind think it is in *any way* normal or humane to keep them permanently in vases and ANY container of water under 5 gallons ( 35litres) . IT IS NOT. It's a vile cruel thing to do to any living thing. These fish require 5 gallons minimum, gently filtered and heated, and heavily planted. These fish can easily live for 5 years + when kept properly. If ANYONE IS not keeping a betta in this environment or larger, then they are not only doing it wrong, they are being ignorant and cruel. AS FOR GOLDFISH - THIS APPLIES TO ANYONE WHO HAS WON ONE FROM A FAIR OR BOUGHT ONE BECAUSE THEY FELT LIKE HAVING A SUPPOSEDLY "EASY" PET- Goldfish are a type of carp. Carp are large fish. Goldfish have an adult length of anything from 8-14 INCHES in length. Go and get a tape measure, and measure that out. Does an 8 inch fish fit into a small bowl or 2 foot tank ? NO. This is basic maths. BABY GOLDFISH NEED SPACE TO GROW. GOLDFISH HAVE A LIFESPAN OF OVER 20 YEARS WHEN KEPT CORRECTLY. Are you stupid enough to think that this 8 inch fish, kept in a small bowl or small tank, eating and making waste, with no filter to remove that waste and no fresh water each week... will live for a long time? NO. Of course it won't. Not only do baby goldfish need space to grow, if you do not give them that space FROM DAY ONE , YOU will be the one forcing their bodies to stunt in growth. Forcing internal organs meant for an 8-14 inch body, into a 3-4 inch body. Goldfish produce a LOT of bodily waste. ALL fish tanks require a filter. Goldfish require at least one LARGE *external* filter, preferably two. And you still need to change 50% of the water every single week to keep the water healthy. If you do not provide filtration, and do not change the water of the tank, YOU are poisoning your fish by forcing it so swim, eat, breathe in, and exists in it;s own bodily waste. It is effectively like being made to live in your own toilet with no fresh air supply or cleaning. Sound good? So to make this really simple if you were too much of a moron to understand the above - If you kept your goldfish in a tank less than 4 feet long ( 55 gallons, 100 gallons or more is better ) , with no external filter, and less than 50% weekly water changes, then *you are killing that fish* . That is why your fair won goldfish lived a few weeks. If you cannot provide the correct space and care for any species , you should not own it.
