Poisoned?

[xDoubtful]

My cat has recently died. He was a year and a half. I wasn't sure if he was poisoned or not but my neighbor said he might have been poisoned with Anti-Freeze.. When he died his eyes were heavily dialated and he was having seizures on and off. Are those side-effects of poison? We let him out half and hour earlier before this happened, then when we let him back inside he started acting like weird (twitching on the ground, unsteadiness, hissing, dialated eyes, ect.).

Hi xDoubtful,

I am very sorry to hear about your cat passing away in February.
Please do not let out any future cat you may end up having.
There are so many dangers outside including other animals, the
danger of being run over, being poisoned etc. Cats don't need to
be let outside. We have a cat too. He's adopted, actually a rescue
cat. I had to promise the rescue society that we would never let
him outside. This was an easy promise because we've never let our
cats outside. Again, sorry for the loss of your cat. Your cat probably
was poisoned based on the symptoms you described. Poor kitty :(

Antifreeze can leak out of radiators, and cats will drink it because they like the sweet taste.  But I don't know if leaking radiators are that common.  Google "antifreeze poisoning in cats" and see what it says.
