I have noticed the past couple of days they don't seem to be eating as much in the evenings.
Does your Chachi seem like he has "baby fat"? Since he is about the same size and age I am just curious. That is what has me wondering if they are eating too much... the little porkers!
Their bodies aren't long, but they do feel heavy when I pick them up. (fat bellies)
Kinda like a water balloon- not much size, but a lot of weight!
