It's best not to offer watery veggies at all when he's a youngster and in moderation when he's older. Iceberg lettuce is a BIG no-no for their entire life.

I think mixing the yogurt with some fresh fruit would be OK for him. Edit: I seem to remember reading somewhere that citrus can contribute to urine crystals, so maybe banana would be a better fruit to mix with his yogurt. I don't have any personal experience with this, it's just something I think I remember...

My favorite brinds of small animal food are Harry Hamster, Volkman and Harlan Teklad. Harlan can be expensive and hard to get though. >.< I hope one of the other hammy owners on here jumps in with what they feed their little critters, 'cause I'm not sure what's available except at the one store I worked at.

I liked to take out the sunflower seeds in my hammy's mixes and use them as treats when I was handling them, so they learned that this was a _special_ treat for when they were being friendly. I used various types of birdseed with my little fellows, I would scatter a tablespoon or so in the bedding and watch them dig it up and stuff it in their cheek pouches...CUTE!! No-sunflower cockatiel seed seemed to work best.

As far as I know, hamsters don't _need_ hay, and if allergies are a problem in your house, it might be best not to bring in loose hay. If you do opt for somethough, go with Timothy.

Diet for small rodents is one of the biggest arguments in pet forums...my old rat forum was scary at times...they would outright attack people for feeding seed mixes and whatnot.. 0_0
