if he was locked away in a garage, he may have drank anti-freeze. the symptomology sounds somewhat similar.

symptoms of antifreeze poisoning

Positive vibes are being sent to Tigger from myself and my furry children

The adventurer kitty returns, huzzah! That was quite an explore for Tigger. When I first saw the title of the thread I was nervous about what I might read. I'm so happy for you and your family. Thanks for the update and I hope Tigger heals quickly.

Yeah for kitty return!

Susan had a cat named Tiger who jumped into the bed of the family pickup (under the tonneau cover) while the vehicle was being packed for a Christmas trip to see Grandma in Las Vegas. Prior to closing the tailgate, dad gave a few loud raps on the cover to make sure there were no kitties. This scared Tiger who didn't move (though no one knew this).

As they stopped in Barstow for a potty break, they heard a very faint "mew" coming from the bed of the truck. After a frantic search, Tiger was located, scared and very cold, but otherwise none the worse for wear. He rode in the (already cramped) cab of the truck the rest of the way to Vegas.

accidentally closed one we had between the steel screen door and the front door once. :rolleyes:

the mailman actually knocked on the door to let us know there was a cat sleeping in the little 3 inch wide gap between the two. she did indeed look like we'd woken her up

It is always remarkable how kitties can flatten themselves, it's like their bones can hook and reconnect at will.

Tango is no longer the lithe girl she was 2 years back, she's gotten (quite happily) fat at 14 lbs. Last night, she managed to get underneath my filing cabinet to hunt down and destroy a spider and it's tight down there. She can also kitty limbo under the open shower door because I really can never go use the bathroom alone. She won't user her box if I'm in there (it's in the bathtub) but god forbid I can go use the loo in private (it's the en suite).

When Tigger first went missing, I checked often at the front door that also has one of those security screens. Our other cat, Dopey (because she is!) was at the door looking for him as well. I didn't know this, and shut the door pinning her in the three inches there. I walked back to the living room and sat down and heard her yelling (she has a loud meow) and opened the door to find her there. She looked at me like WTF? :p
No, I asked. His kidney count was about 80 when normal should be 30, so only slightly elevated. Glycol poisoning would cause the count to be 260-300, which is deadly. Also, he has no nausia, diareha, or vomitting. In fact he is eating, which he most likely wouldn't do if it were antifreeze. So thank goodness, but that has been ruled out.

Well, thank goodness for that! C'mon Tigger, we're all pulling for you!
