I am a first time kitty owner, I've had Jubei for 3 days now. I took him in to get his 1st shot today, & the vet had reccommeded Science Diet for him. What I forgot to ask is which is better, dry or wet food? Should I give him both? Right now I'm giving him both, I just want to make sure I'm doing the best thing for him. Any suggestions?? Thank you!
