metacharacters and if-then statements

[Agent-X]

I'm trying to use this script, but it's not working:

ubuntu@ubuntu:~/Desktop$ cat ./script.sh 
#!/bin/sh
if [ -e ./000[0-9].cat ]
then
echo "meow"
else
echo "woof"
fi
ubuntu@ubuntu:~/Desktop$ bash -x ./script.sh 
+ '[' -e ./0000.cat ./0001.cat ./0009.cat ']'
./script.sh: line 2: [: too many arguments
+ echo woof
woof

Is there a proper way to do this?
I have files 0000.cat 0001.cat 0009.cat and 0010.cat

go through every .cat file

for F in *cat
do
 case $F in
    000[0-9]* ) echo "meow" ;;
    * ) echo "sdfs";;
  esac
done
