Thank you all so much for your replys, they have been full of great advice
My cat Felix has had semi-skimmed milk for quite sometime,his health is good and hes nearly 16 .Felix has canned soft food because he only has 2 teeth left and he likes cooked chicken as a treat, but the pieces have to be small.
My mum yesterday has wormed felix,he had the powder with a bit of tuna, and he ate it all up.
I think felix just likes his food too much, hes still climbing fences and chasing off boy cats, but I,ll make sure he dos,nt get too fat. Thankyou again
