Last weekend, I started switching from Science diet to Evo cat food because I heard all the terrible things about Science diet and Evo seemed like a good one to switch to and I must say I'm glad I switched! My cat use to meow and howl almost 24/7 but now he's drastically changed. He does still meow every now and than but its definitely not as bad but he's also sleeping more during the day, is this a good thing? or was it wrong that I switched food? I'm a bit confused.
