Nestlé has raised its prices by 5.2% in the first three months of this year - and has warned of more increases to come.
Prices set by the food and drink manufacturer rose 7.7% for its pet products, followed by water, up 7.2%, while confectionery rose 3%.
Nestlé is the brand behind household names including Purina PetCare, Nespresso and KitKat.
Mark Schneider, its chief executive, said: “Cost inflation continues to increase sharply, which will require further pricing and mitigating actions over the course of the year.
“In these first months of the year, the war in Ukraine has caused unspeakable human suffering.“
He continued: “We remain focused on supporting our colleagues there and providing humanitarian relief, while standing with the international community in the call for peace.”
Nestlé confirmed it expected to meet full-year sales and profit targets but said it increased prices “in a responsible manner” to reflect significant cost inflation.

Matt Britzman, an equity analyst at Hargreaves Lansdown, said: “Hiking prices to keep things moving in the right direction in the wake of input cost inflation certainly won’t be a course of action management want to have to take.
“But nonetheless, it’s the position Nestlé finds itself in and doesn’t look likely to go away anytime soon.”
“So far, volumes have still been able to move in the right direction aided by the recovery in out-of-home channels that saw demand drop off while restrictions were in place last year.“
It comes as shoppers have been venting their frustration over “empty shelves” after major supermarkets started rationing bottles of cooking oil.
Tesco is allowing shoppers to purchase only three items each, while Waitrose and Morrisons have restricted shoppers to two items each.
The limits include olive, rapeseed and sunflower oils, with restrictions being placed both in-store and online.
Sainsbury's and Asda currently have no restrictions on how much cooking oil customers can buy.
The product limits are linked to the ongoing Russian invasion of Ukraine. Both countries produce most of the world's sunflower oil and the war is disrupting exports.
The price of cooking oils in shops reportedly around 20% higher than they were a year ago.
As well as being a cupboard staple, sunflower oil is also found in hundreds of products from biscuits, crisps, mayonnaise and ready meals.
Tom Lock, founder of The British Snack Company, which makes hand-cooked crisps for sale in pubs, told The Guardian that after potatoes, its other vital ingredient was sunflower oil.
