Should i be worried?

[magic]

I have a leopard gecko that is about 4 years old. Recently he seems to be gettin kinda slower and not catching as many crickets. Now im gettin real worried that he is catching either 0 or very few crickets. He also used to love being hand fed mealworms, now he wont take them. He still looks very healthy and has the fat tail. But should i be worried that hes not gettin enough food?

try taking the back legs off the crickets and he should be able to catch them now but he may not want to because reptiles seem to not like slow moving insects worth a try though

Try a big moth, if he goes after it you Know he just needs variety.
