We picked up our new brother and sister 9 week old babies yesterday. They've settled in really well, super friendly and confident, but the boy (who is small anyway) has not eaten anything since we brought him him at lunchtime yesterday. I've offered the same food they were eating, plus a different dry kind (Hills) plus wet food, but he just sniffs it.
I know it can take a while in a new home (and neither have used the litter trays so far despite being toilet trained) but should I call the vet?
Any advice please? Very worried.
