>>My grey rat had not eaten since I switched him from pink/fussies to hoppers. I don't think the size is too big, but he did not eat for 4 weeks. I figured it was just the changing of the season, but I kept trying.
Some snakes have a hard time adjusting to a change in the diet or even how the food is presented. Snakes that are used to prey without hair may not take right away to a fully furred prey item. Keep trying with the fuzzies but instead of feeding multiples, try one fuzzy and one hopper....rub the fuzzy over the hopper too.
I have a coworker with a young black rat snake that took over four months to get over its fear of the furry food but finally started accepting hoppers. I have a yearling jungle corn I am in the process of introducing to very small fully furred hoppers as he's getting big enough now to start thinking about switching food sizes. Normally he slams food before I can even get it into the cage (very agressive feeding response - the kingsnake blood in him lol). However the first time I tried a hopper with him almost 2 weeks ago, it royally confused the heck out of him. He spent a solid 10 minutes poking and examining the hopper before it finally clicked in his brain that it was 'food'.. then his reaction was what I expected.. slammed it. LOL.
I recently sold my gray rat snake to my coworker only to find out that snake had a feeding issue I didn't even realize she had. Since he took her, she would not eat for him at all..she'd strike at the food then ignore it. It took a couple weeks until we figured out that she was missing something of hers - a small plastic critter cage that I had always kept in her old setup. She liked to sleep in it even though it was clear/see-through plastic. Even though you could see her in the container, I guess it made her feel safe - her "security blanket". After thinking back on it, she also seemed to eat most of her meals in that container too. I gave him the container this past weekend and sure enough the next day she took two mice without a fuss.
