Below are some recent questions we've received regarding Hills Science Plan Senior Chicken Cat Food, including answers from our team.
Elaine
Hello
Our vet doesn't sell Hills Science Plan 11+ for cats so have always bought the senior/7+ for our cat (male); a rescue cat guessed to be 12 yrs old by vet. She advised a supplement of omega 3 and 6 for his dry skin (not hugely dry; and fur is very silky) but I am wondering if there would be an improvement if I switch to the 11+ Science plan dry biscuits without the supplement.
Many thanks
Unless your cat has an unusually high requirement for these oils, this Hills diet should contain adequate levels. I would suggest trying the diet just as it is. If you notice any change in the skin then it is possible to add supplements to it, but this is not usually necessary. Changing the rest of the diet can alter the overall balance of many things and supplements which were previously of benefit, might not now be needed.
