Feeding my older snake .

[Tracy33]

Hi guys , have not been on for a while .
I have a question about my CP . I don't know if its he's age or what , but he only seems to eat a rat , maybe every 2 to 3 months . I tried another rat tonight and he does not want it again . I hold the rat for about 20 mins , and he keeps smelling it , but does not take it . It seems , he just wants to climb up on me .
The rats i am throwing away is mad .
He last eat just over 2 months ago , he eat 2 rats . The thing is , i just can,t see the sign's any more , that he is hungry .
Btw , i should point out that he will be 17 yrs old , this coming October .
Is this an age thing , he used to strike and eat more regular .
Any advice would be great .
