I’m by no means an expert; i looked up the composition of that same brand in another ebay listing, it says:
Composition: Cereals, Meat and Animal Derivatives, Derivatives of Vegetable Origin, Oils and Fats, Mineral, Yeasts.
Analytical Constituents: Protein: 30%, Fat Content: 10%, Crude Fibre: 3.5%, Inorganic Matter: 8%, Moisture: 10%
Seems like the main constituent would be cereals? Roughly similar to the Whiskas 1+ we too have, so i guess it would be fine?
You can try a 300 grm ‘trial dose’ to test it out with the hogs: https://www.ebay.co.uk/itm/323487707159?epid=1504302615&hash=item4b515eb017:g:Ox4AAOSw~7dfIxr6&amdata=enc%3AAQAHAAAA8HLQTNi5oHPhCtGZaF%2Bl0kbUOEK2QrnqyrBPr4xG03iq5xgJfiIFJaB3jqCvaZQ8MAlFqquyfcEOSv3ID%2BvQ1J8aHjvsvLO8c1pf0b4%2Fo9rZST2Ql4UtxnrpAN2lGTALgFnAal3MIO9D63vnuITSrNYMuM3ec%2FfDJrlmdmhwfaCrUZ7z%2BSu5ocOrMmRQd2saByO58BIeYCG6ljZ79uskX8K6ixRhO2XK7Y2cuz2VT9E1rHVTMtprTB6m8CphnufnRUanbBP0xxDvMGq6lzPsBOsSGcXhLiCFM9%2FztrBYahJ%2FkCbkikgBx466E4iQ6SxW3Q%3D%3D%7Ctkp%3ABFBMkuistYNh
I might give it a try too, to save on the whiskas.
