Daniel has shown to be very allergic to cats and we just discovered very alergic to cat urine.
This is very sad. Especially after seeing him how he loves the kitten. I am sure that he would have been a very good cat owner. But I am happy to read that you have not had to go to the hospital with him, and that the kitten will be well taken care of.
Have a nice day and have a nice weekend.
All the best. Greetings and much love from Hungary.
